Run OpenClaw Agents on Azure Linux VMs (with Secure Defaults)
Many teams want an enterprise-ready personal AI assistant, but they need it on infrastructure they control, with security boundaries they can explain to IT. That is exactly where OpenClaw fits on Azure. OpenClaw is a self-hosted, always-on personal agent runtime you run in your enterprise environment and Azure infrastructure. Instead of relying only on a hosted chat app from a third-party provider, you can deploy, operate, and experiment with an agent on an Azure Linux VM you control — using your existing GitHub Copilot licenses, Azure OpenAI deployments, or API plans from OpenAI, Anthropic Claude, Google Gemini, and other model providers you already subscribe to. Once deployed on Azure, you can interact with an OpenClaw agent through familiar channels like Microsoft Teams, Slack, Telegram, WhatsApp, and many more! For Azure users, this gives you a practical middle ground: modern personal-agent workflows on familiar Azure infrastructure. What is OpenClaw, and how is it different from ChatGPT/Claude/chat apps? OpenClaw is a self-hosted personal agent runtime that can be hosted on Azure compute infrastructure. How it differs: ChatGPT/Claude apps are primarily hosted chat experiences tied to one provider's models OpenClaw is an always-on runtime you operate yourself, backed by your choice of model provider — GitHub Copilot, Azure OpenAI, OpenAI, Anthropic Claude, Google Gemini, and others OpenClaw lets you keep the runtime boundary in your own Azure VM environment within your Azure enterprise subscription In practice, OpenClaw is useful when you want a persistent assistant for operational and workflow tasks, with your own infrastructure as the control point. You bring whatever model provider and API plan you already have — OpenClaw connects to it. Why Azure Linux VMs? Azure Linux VMs are a strong fit because they provide: A suitable host machine for the OpenClaw agent to run on Enterprise-friendly infrastructure and identity workflows Repeatable provisioning via the Azure CLI Network hardening with NSG rules Managed SSH access through Azure Bastion instead of public SSH exposure How to Set Up OpenClaw on an Azure Linux VM This guide sets up an Azure Linux VM, applies NSG (Network Security Group) hardening, configures Azure Bastion for managed SSH access, and installs an always-on OpenClaw agent within the VM that you can interact with through various messaging channels. What you'll do Create Azure networking (VNet, subnets, NSG) and compute resources with the Azure CLI Apply Network Security Group rules so VM SSH is allowed only from Azure Bastion Use Azure Bastion for SSH access (no public IP on the VM) Install OpenClaw on the Azure VM Verify OpenClaw installation and configuration on the VM What you need An Azure subscription with permission to create compute and network resources Azure CLI installed (install steps) An SSH key pair (the guide covers generating one if needed) ~20–30 minutes Configure deployment Step 1: Sign in to Azure CLI az login # Select a suitable Azure subscription during Azure login az extension add -n ssh # SSH extension is required for Azure Bastion SSH The ssh extension is required for Azure Bastion native SSH tunneling. Step 2: Register required resource providers (one-time) Register required Azure Resource Providers (one time registration): az provider register --namespace Microsoft.Compute az provider register --namespace Microsoft.Network Verify registration. Wait until both show Registered. az provider show --namespace Microsoft.Compute --query registrationState -o tsv az provider show --namespace Microsoft.Network --query registrationState -o tsv Step 3: Set deployment variables Set the deployment environment variables that will be needed throughout this guide. RG="rg-openclaw" LOCATION="westus2" VNET_NAME="vnet-openclaw" VNET_PREFIX="10.40.0.0/16" VM_SUBNET_NAME="snet-openclaw-vm" VM_SUBNET_PREFIX="10.40.2.0/24" BASTION_SUBNET_PREFIX="10.40.1.0/26" NSG_NAME="nsg-openclaw-vm" VM_NAME="vm-openclaw" ADMIN_USERNAME="openclaw" BASTION_NAME="bas-openclaw" BASTION_PIP_NAME="pip-openclaw-bastion" Adjust names and CIDR ranges to fit your environment. The Bastion subnet must be at least /26. Step 4: Select SSH key Use your existing public key if you have one: SSH_PUB_KEY="$(cat ~/.ssh/id_ed25519.pub)" If you don't have an SSH key yet, generate one: ssh-keygen -t ed25519 -a 100 -f ~/.ssh/id_ed25519 -C "you@example.com" SSH_PUB_KEY="$(cat ~/.ssh/id_ed25519.pub)" Step 5: Select VM size and OS disk size VM_SIZE="Standard_B2as_v2" OS_DISK_SIZE_GB=64 Choose a VM size and OS disk size available in your subscription and region: Start smaller for light usage and scale up later Use more vCPU/RAM/disk for heavier automation, more channels, or larger model/tool workloads If a VM size is unavailable in your region or subscription quota, pick the closest available SKU List VM sizes available in your target region: az vm list-skus --location "${LOCATION}" --resource-type virtualMachines -o table Check your current vCPU and disk usage/quota: az vm list-usage --location "${LOCATION}" -o table Deploy Azure resources Step 1: Create the resource group The Azure resource group will contain all of the Azure resources that the OpenClaw agent needs. az group create -n "${RG}" -l "${LOCATION}" Step 2: Create the network security group Create the NSG and add rules so only the Bastion subnet can SSH into the VM. az network nsg create \ -g "${RG}" -n "${NSG_NAME}" -l "${LOCATION}" # Allow SSH from the Bastion subnet only az network nsg rule create \ -g "${RG}" --nsg-name "${NSG_NAME}" \ -n AllowSshFromBastionSubnet --priority 100 \ --access Allow --direction Inbound --protocol Tcp \ --source-address-prefixes "${BASTION_SUBNET_PREFIX}" \ --destination-port-ranges 22 # Deny SSH from the public internet az network nsg rule create \ -g "${RG}" --nsg-name "${NSG_NAME}" \ -n DenyInternetSsh --priority 110 \ --access Deny --direction Inbound --protocol Tcp \ --source-address-prefixes Internet \ --destination-port-ranges 22 # Deny SSH from other VNet sources az network nsg rule create \ -g "${RG}" --nsg-name "${NSG_NAME}" \ -n DenyVnetSsh --priority 120 \ --access Deny --direction Inbound --protocol Tcp \ --source-address-prefixes VirtualNetwork \ --destination-port-ranges 22 The rules are evaluated by priority (lowest number first): Bastion traffic is allowed at 100, then all other SSH is blocked at 110 and 120. Step 3: Create the virtual network and subnets Create the VNet with the VM subnet (NSG attached), then add the Bastion subnet. az network vnet create \ -g "${RG}" -n "${VNET_NAME}" -l "${LOCATION}" \ --address-prefixes "${VNET_PREFIX}" \ --subnet-name "${VM_SUBNET_NAME}" \ --subnet-prefixes "${VM_SUBNET_PREFIX}" # Attach the NSG to the VM subnet az network vnet subnet update \ -g "${RG}" --vnet-name "${VNET_NAME}" \ -n "${VM_SUBNET_NAME}" --nsg "${NSG_NAME}" # AzureBastionSubnet — name is required by Azure az network vnet subnet create \ -g "${RG}" --vnet-name "${VNET_NAME}" \ -n AzureBastionSubnet \ --address-prefixes "${BASTION_SUBNET_PREFIX}" Step 4: Create the Virtual Machine Create the VM with no public IP. SSH access for OpenClaw configuration will be exclusively through Azure Bastion. az vm create \ -g "${RG}" -n "${VM_NAME}" -l "${LOCATION}" \ --image "Canonical:ubuntu-24_04-lts:server:latest" \ --size "${VM_SIZE}" \ --os-disk-size-gb "${OS_DISK_SIZE_GB}" \ --storage-sku StandardSSD_LRS \ --admin-username "${ADMIN_USERNAME}" \ --ssh-key-values "${SSH_PUB_KEY}" \ --vnet-name "${VNET_NAME}" \ --subnet "${VM_SUBNET_NAME}" \ --public-ip-address "" \ --nsg "" --public-ip-address "" prevents a public IP from being assigned. --nsg "" skips creating a per-NIC NSG (the subnet-level NSG created earlier handles security). Reproducibility: The command above uses latest for the Ubuntu image. To pin a specific version, list available versions and replace latest: az vm image list \ --publisher Canonical --offer ubuntu-24_04-lts \ --sku server --all -o table Step 5: Create Azure Bastion Azure Bastion provides secure-managed SSH access to the VM without exposing a public IP. Bastion Standard SKU with tunneling is required for CLI-based "az network bastion ssh" command. az network public-ip create \ -g "${RG}" -n "${BASTION_PIP_NAME}" -l "${LOCATION}" \ --sku Standard --allocation-method Static az network bastion create \ -g "${RG}" -n "${BASTION_NAME}" -l "${LOCATION}" \ --vnet-name "${VNET_NAME}" \ --public-ip-address "${BASTION_PIP_NAME}" \ --sku Standard --enable-tunneling true Bastion provisioning typically takes 5–10 minutes but can take up to 15–30 minutes in some regions. Step 6: Verify Deployments After all resources are deployed, your resource group should look like the following: Install OpenClaw Step 1: SSH into the VM through Azure Bastion VM_ID="$(az vm show -g "${RG}" -n "${VM_NAME}" --query id -o tsv)" az network bastion ssh \ --name "${BASTION_NAME}" \ --resource-group "${RG}" \ --target-resource-id "${VM_ID}" \ --auth-type ssh-key \ --username "${ADMIN_USERNAME}" \ --ssh-key ~/.ssh/id_ed25519 Step 2: Install OpenClaw (in the Bastion SSH shell) curl -fsSL https://openclaw.ai/install.sh | bash The installer installs Node LTS and dependencies if not already present, installs OpenClaw, and launches the OpenClaw onboarding wizard. For more information, see the open source OpenClaw install docs. OpenClaw Onboarding: Choosing an AI Model Provider During OpenClaw onboarding, you'll choose the AI model provider for the OpenClaw agent. This can be GitHub Copilot, Azure OpenAI, OpenAI, Anthropic Claude, Google Gemini, or another supported provider. See the open source OpenClaw install docs for details on choosing an AI model provider when going through the onboarding wizard. Most enterprise Azure teams already have GitHub Copilot licenses. If that is your case, we recommend choosing the GitHub Copilot provider in the OpenClaw onboarding wizard. See the open source OpenClaw docs on configuring GitHub Copilot as the AI model provider. OpenClaw Onboarding: Setting up Messaging Channels During OpenClaw onboarding, there will be an optional step where you can set up various messaging channels to interact with your OpenClaw agent. For first time users, we recommend setting up Telegram due to ease of setup. Other messaging channels such as Microsoft Teams, Slack, WhatsApp, and others can also be set up. To configure OpenClaw for messaging through chat channels, see the open source OpenClaw chat channels docs. Step 3: Verify OpenClaw Configuration To validate that everything was set up correctly, run the following commands within the same Bastion SSH session: openclaw status openclaw gateway status If there are any issues reported, you can run the onboarding wizard again with the steps above. Alternatively, you can run the following command: openclaw doctor Message OpenClaw Once you have configured the OpenClaw agent to be reachable via various messaging channels, you can verify that it is responsive by messaging it. Enhancing OpenClaw for Use Cases There you go! You now have a 24/7, always-on personal AI agent, living on its own Azure VM environment. For awesome OpenClaw use cases, check out the awesome-openclaw-usecases repository. To enhance your OpenClaw agent with additional AI skills so that it can autonomously perform multi-step operations on any domain, check out the awesome-openclaw-skills repository. You can also check out ClawHub and ClawSkills, two popular open source skills directories that can enhance your OpenClaw agent. Cleanup To delete all resources created by this guide: az group delete -n "${RG}" --yes --no-wait This removes the resource group and everything inside it (VM, VNet, NSG, Bastion, public IP). This also deletes the OpenClaw agent running within the VM. If you'd like to dive deeper about deploying OpenClaw on Azure, please check out the open source OpenClaw on Azure docs.

Security is more important than ever. The industry-standard for secure machine configuration is the Center for Internet Security (CIS) Benchmarks. These benchmarks provide consensus-based prescriptive guidance to help organizations harden diverse systems, reduce risk, and streamline compliance with major regulatory frameworks and industry standards like NIST, HIPAA, and PCI DSS. In our previous post, we outlined our plans to improve the Linux server compliance and hardening experience on Azure and shared a vision for integrating CIS Benchmarks. Today, that vision has turned into reality. We're now announcing the next phase of this work: Center for Internet Security (CIS) Benchmarks are now available on Azure for all Azure endorsed distros, at no additional cost to Azure and Azure Arc customers. With today's announcement, you get access to the CIS Benchmarks on Azure with full parity to what’s published by the Center for Internet Security (CIS). You can adjust parameters or define exceptions, tailoring security to your needs and applying consistent controls across cloud, hybrid, and on-premises environments - without having to implement every control manually. Thanks to this flexible architecture, you can truly manage compliance as code. How we achieve parity To ensure accuracy and trust, we rely on and ingest CIS machine-readable Benchmark content (OVAL/XCCDF files) as the source of truth. This guarantees that the controls and rules you apply in Azure match the official CIS specifications, reducing drift and ensuring compliance confidence. What’s new under the hood At the core of this update is azure-osconfig’s new compliance engine - a lightweight, open-source module developed by the Azure Core Linux team. It evaluates Linux systems directly against industry-standard benchmarks like CIS, supporting both audit and, in the future, auto-remediation. This enables accurate, scalable compliance checks across large Linux fleets. Here you can read more about azure-osconfig. Dynamic rule evaluation The new compliance engine supports simple fact-checking operations, evaluation of logic operations on them (e.g., anyOf, allOf) and Lua based scripting, which allows to express complex checks required by the CIS Critical Security Controls - all evaluated natively without external scripts. Scalable architecture for large fleets When the assignment is created, the Azure control plane instructs the machine to pull the latest Policy package via the Machine Configuration agent. Azure-osconfig’s compliance engine is integrated as a light-weight library to the package and called by Machine Configuration agent for evaluation – which happens every 15-30minutes. This ensures near real-time compliance state without overwhelming resources and enables consistent evaluation across thousands of VMs and Azure Arc-enabled servers. Future-ready for remediation and enforcement While the Public Preview starts with audit-only mode, the roadmap includes per-rule remediation and enforcement using technologies like eBPF for kernel-level controls. This will allow proactive prevention of configuration drift and runtime hardening at scale. Please reach out if you interested in auto-remediation or enforcement. Extensibility beyond CIS Benchmarks The architecture was designed to support other security and compliance standards as well and isn’t limited to CIS Benchmarks. The compliance engine is modular, and we plan to extend the platform with STIG and other relevant industry benchmarks. This positions Azure as a platform for a place where you can manage your compliance from a single control-plane without duplicating efforts elsewhere. Collaboration with the CIS This milestone reflects a close collaboration between Microsoft and the CIS to bring industry-standard security guidance into Azure as a built-in capability. Our shared goal is to make cloud-native compliance practical and consistent, while giving customers the flexibility to meet their unique requirements. We are committed to continuously supporting new Benchmark releases, expanding coverage with new distributions and easing adoption through built-in workflows, such as moving from your current Benchmark version to a new version while preserving your custom configurations. Certification and trust We can proudly announce that azure-osconfig has met all the requirements and is officially certified by the CIS for Benchmark assessment, so you can trust compliance results as authoritative. Minor benchmark updates will be applied automatically, while major version will be released separately. We will include workflows to help migrate customizations seamlessly across versions. Key Highlights Built-in CIS Benchmarks for Azure Endorsed Linux distributions Full parity with official CIS Benchmarks content and certified by the CIS for Benchmark Assessment Flexible configuration: adjust parameters, define exceptions, tune severity Hybrid support: enforce the same baseline across Azure, on-prem, and multi-cloud with Azure Arc Reporting format in CIS tooling style Supported use cases Certified CIS Benchmarks for all Azure Endorsed Distros - Audit only (L1/L2 server profiles) Hybrid / On-premises and other cloud machines with Azure Arc for the supported distros Compliance as Code (example via Github -> Azure OIDC auth and API integration) Compatible with GuestConfig workbook What’s next? Our next mission is to bring the previously announced auto-remediation capability into this experience, expand the distribution coverage and elevate our workflows even further. We’re focused on empowering you to resolve issues while honoring the unique operational complexity of your environments. Stay tuned!

Organizations across government (including local and federal agencies and their contractors), finance, healthcare, and other regulated industries running workloads on Microsoft Azure now have a streamlined path to meet rigorous FIPS 140-3 compliance requirements. Canonical is pleased to announce the availability of Ubuntu Pro FIPS 22.04 LTS on the Azure Marketplace, featuring newly certified cryptographic modules. This offering extends the stability and comprehensive security features of Ubuntu Pro, tailored for state agencies, federal contractors, and industries requiring a FIPS-validated foundation on Azure. It provides the enterprise-grade Ubuntu experience, optimized for performance on Azure in collaboration with Microsoft, and enhanced with critical compliance capabilities. For instance, if you are building a Software as a Service (SaaS) application on Azure that requires FedRAMP authorization, utilizing Ubuntu Pro FIPS 22.04 LTS can help you meet specific controls like SC-13 (Cryptographic Protection), as FIPS 140-3 validated modules are a foundational requirement. This significantly streamlines your path to achieving FedRAMP compliance. What is FIPS 140-3 and why does it matter? FIPS 140-3 is the latest iteration of the benchmark U.S. government standard for validating cryptographic module implementations, superseding FIPS 140-2. Managed by NIST, it's essential for federal agencies and contractors and is a recognized best practice in many regulated industries like finance and healthcare. Using FIPS-validated components helps ensure cryptography is implemented correctly, protecting sensitive data in transit and at rest. Ubuntu Pro FIPS 22.04 LTS includes FIPS 140-3 certified versions of the Linux kernel and key cryptographic libraries (like OpenSSL, Libgcrypt, GnuTLS) pre-enabled, which are drop-in replacements for the standard packages, greatly simplifying deployment for compliance needs. The importance of security updates (fips-updates) A FIPS certificate applies to a specific module version at its validation time. Over time, new vulnerabilities (CVEs) are discovered in these certified modules. Running code with known vulnerabilities poses a significant security risk. This creates a tension between strict certification adherence and maintaining real-world security. Recognizing this, Canonical provides security fixes for the FIPS modules via the fips-updates stream, available through Ubuntu Pro. We ensure these security patches do not alter the validated cryptographic functions. This approach aligns with modern security thinking, including recent FedRAMP guidance, which acknowledges the greater risk posed by unpatched vulnerabilities compared to solely relying on the original certified binaries. Canonical strongly recommends all users enable the fips-updates repository to ensure their systems are both compliant and secure against the latest threats. FIPS 140-3 vs 140-2 The new FIPS 140-3 standard includes modern ciphers such as TLS v1.3, as well as deprecating older algorithms like MD5. If you are upgrading systems and workloads to FIPS 140-3, it will be necessary to perform rigorous testing to ensure that applications continue to work correctly. Compliance tooling Included Ubuntu Pro FIPS also includes access to Canonical's Ubuntu Security Guide (USG) tooling, which assists with automated hardening and compliance checks against benchmarks like CIS and DISA-STIG, a key requirement for FedRAMP deployments. How to get Ubuntu Pro FIPS on Azure You can leverage Ubuntu Pro FIPS 22.04 LTS on Azure in two main ways: Deploy the Marketplace Image: Launch a new VM directly from the dedicated Ubuntu Pro FIPS 22.04 LTS listing on the Azure Marketplace. This image comes with the FIPS modules pre-enabled for immediate use. Enable on an Existing Ubuntu Pro VM: If you already have an Ubuntu Pro 22.04 LTS VM running on Azure, you can enable the FIPS modules using the Ubuntu Pro Client (pro enable fips-updates). Upgrading standard Ubuntu: If you have a standard Ubuntu 22.04 LTS VM on Azure, you first need to attach Ubuntu Pro to it. This is a straightforward process detailed in the Azure documentation for getting Ubuntu Pro. Once Pro is attached, you can enable FIPS as described above. Learn More Ubuntu Pro FIPS provides a robust, maintained, and compliant foundation for your sensitive workloads on Azure.

As cloud and AI evolve at an unprecedented pace, the need to deliver high-quality, secure, and reliable Linux VM images has never been more essential. Azure Image Testing for Linux (AITL) is a self-service validation tool designed to help developers, ISVs, and Linux distribution partners ensure their images meet Azure’s standards before deployment. With AITL, partners can streamline testing, reduce engineering overhead, and ensure compliance with Azure’s best practices, all in a scalable and automated manner. Let’s explore how AITL is redefining image validation and why it’s proving to be a valuable asset for both developers and enterprises. Before AITL, image validation was largely a manual and repetitive process, engineers were often required to perform frequent checks, resulting in several key challenges: Time-Consuming: Manual validation processes delayed image releases. Inconsistent Validation: Each distro had different methods for testing, leading to varying quality levels. Limited Scalability: Resource constraints restricted the ability to validate a broad set of images. AITL addresses these challenges by enabling partners to seamlessly integrate image validation into their existing pipelines through APIs. By executing tests within their own Azure subscriptions prior to publishing, partners can ensure that only fully validated, high-quality Linux images are promoted to production in the Azure environment. How AITL Works? AITL is powered by LISA, which is a test framework and a comprehensive opensource tool contains 400+ test cases. AITL provides a simple, yet powerful workflow run LISA test cases: Registration: Partners register their images in AITL’s validation framework. Automated Testing: AITL runs a suite of predefined validation tests using LISA. Detailed Reporting: Developers receive comprehensive results highlighting compliance, performance, and security areas. All test logs are available to access. Self-Service Fixes: Any detected issues can be addressed by the partner before submission, eliminating delays and back-and-forth communication. Final Sign-Off: Once tests pass, partners can confidently publish their images, knowing they meet Azure’s quality standards. Benefits of AITL AITL is a transformative tool that delivers significant benefits across the Linux and cloud ecosystem: Self-Service Capability: Enables developers and ISVs to independently validate their images without requiring direct support from Microsoft. Scalable by Design: Supports concurrent testing of multiple images, driving greater operational efficiency. Consistent and Standardized Testing: Offers a unified validation framework to ensure quality and consistency across all endorsed Linux distributions. Proactive Issue Detection: Identifies potential issues early in the development cycle, helping prevent costly post-deployment fixes. Seamless Pipeline Integration: Easily integrates with existing CI/CD workflows to enable fully automated image validation. Use Cases for AITL AITL designed to support a diverse set of users across the Linux ecosystem: Linux Distribution Partners: Organizations such as Canonical, Red Hat, and SUSE can validate their images prior to publishing on the Azure Marketplace, ensuring they meet Azure’s quality and compliance standards. Independent Software Vendors (ISVs): Companies providing custom Linux Images can verify that their custom Linux-based solutions are optimized for performance and reliability on Azure. Enterprise IT Teams: Businesses managing their own Linux images on Azure can use AITL to validate updates proactively, reducing risk and ensuring smooth production deployments. Current Status and Future Roadmap AITL is currently in private preview, with five major Linux distros and select ISVs actively integrating it into their validation workflows. Microsoft plans to expand AITL’s capabilities by adding: Support for Private Test Cases: Allowing partners to run custom tests within AITL securely. Kernel CI Integration: Enhancing low-level kernel validation for more robust testing and results for community. DPDK and Specialized Validation: Ensuring network and hardware performance for specialized SKU (CVM, HPC) and workloads How to Get Started? For developers and partners interested in AITL, following the steps to onboard. Register for Private Preview AITL is currently hidden behind a preview feature flag. You must first register the AITL preview feature with your subscription so that you can then access the AITL Resource Provider (RP). These are one-time steps done for each subscription. Run the “az feature register” command to register the feature: az feature register --namespace Microsoft.AzureImageTestingForLinux --name JobandJobTemplateCrud Sign Up for Private Preview – Contact Microsoft’s Linux Systems Group to request access. Private Preview Sign Up To confirm that your subscription is registered, run the above command and check that properties.state = “Registered” Register the Resource Provider Once the feature registration has been approved, the AITL Resource Provider can be registered by running the “az provider register” command: az provider register --namespace Microsoft.AzureImageTestingForLinux *If your subscription is not registered to Microsoft.Compute/Network/Storage, please do so. These are also prerequisites to using the service. This can be done for each namespace (Microsoft.Compute, Microsoft.Network, Microsoft.Storage) through this command: az provider register --namespace Microsoft.Compute Setup Permissions The AITL RP requires a permission set to create test resources, such as the VM and storage account. The permissions are provided through a custom role that is assigned to the AITL Service Principal named AzureImageTestingForLinux. We provide a script setup_aitl.py to make it simple. It will create a role and grant to the service principal. Make sure the active subscription is expected and download the script to run in a python environment. https://raw.githubusercontent.com/microsoft/lisa/main/microsoft/utils/setup_aitl.py You can run the below command: python setup_aitl.py -s "/subscriptions/xxxx" Before running this script, you should check if you have the permission to create role definition in your subscription. *Note, it may take up to 20 minutes for the permission to be propagated. Assign an AITL jobs access role If you want to use a service principle or registration application to call AITL APIs. The service principle or App should be assigned a role to access AITL jobs. This role should include the following permissions: az role definition create --role-definition '{ "Name": "AITL Jobs Access Role", "Description": "Delegation role is to read and write AITL jobs and job templates", "Actions": [ "Microsoft.AzureImageTestingForLinux/jobTemplates/read", "Microsoft.AzureImageTestingForLinux/jobTemplates/write", "Microsoft.AzureImageTestingForLinux/jobTemplates/delete", "Microsoft.AzureImageTestingForLinux/jobs/read", "Microsoft.AzureImageTestingForLinux/jobs/write", "Microsoft.AzureImageTestingForLinux/jobs/delete", "Microsoft.AzureImageTestingForLinux/operations/read", "Microsoft.Resources/subscriptions/read", "Microsoft.Resources/subscriptions/operationresults/read", "Microsoft.Resources/subscriptions/resourcegroups/write", "Microsoft.Resources/subscriptions/resourcegroups/read", "Microsoft.Resources/subscriptions/resourcegroups/delete" ], "IsCustom": true, "AssignableScopes": [ "/subscriptions/01d22e3d-ec1d-41a4-930a-f40cd90eaeb2" ] }' You can create a custom role using the above command in the cloud shell, and assign this role to the service principle or the App. All set! Please go through a quick start to try AITL APIs. Download AITL wrapper AITL is served by Azure management API. You can use any REST API tool to access it. We provide a Python wrapper for better experience. The AITL wrapper is composed of a python script and input files. It calls “az login” and “az rest” to provide similar experience like the az CLI. The input files are used for creating test jobs. Make sure az CLI and python 3 are installed. Clone LISA code, or only download files in the folder. lisa/microsoft/utils/aitl at main · microsoft/lisa (github.com). Use the command below to check the help text. python -m aitl job –-help python -m aitl job create --help Create a job Job creation consists of two entities: A job template and an image. The quickest way to get started with the AITL service is to create a Job instance with your job template properties in the request body. Replace placeholders with the real subscription id, resource group, job name to start a test job. This example runs 1 test case with a marketplace image using the tier0.json template. You can create a new json file to customize the test job. The name is optional. If it’s not provided, AITL wrapper will generate one. python -m aitl job create -s {subscription_id} -r {resource_group} -n {job_name} -b ‘@./tier0.json’ The default request body is: { "location": "westus3", "properties": { "jobTemplateInstance": { "selections": [ { "casePriority": [ 0 ] } ] } } } This example runs the P0 test cases with the default image. You can choose to add fields to the request, such as image to test. All possible fields are described in the API Specification – Jobs section. The “location” property is a required field that represents the location where the test job should be created, it doesn’t affect the location of VMs. AITL supports “westus”, “westus2”, or “westus3”. The image object in the request body json is where the image type to be used for testing is detailed, as well as the CPU architecture and VHD Generation. If the image object is not included, LISA will pick a Linux marketplace image that meets the requirements for running the specified tests. When an image type is specified, additional information will be required based on the image type. Supported image types are VHD, Azure Marketplace image, and Shared Image Gallery. - VHD requires the SAS URL. - Marketplace image requires the publisher, offer, SKU, and version. - Shared Image Gallery requires the gallery name, image definition, and version. Example of how to include the image object for shared image gallery. (<> denotes placeholder): { "location": "westus3", “properties: { <...other properties from default request body here>, "image": { "type": "shared_gallery", "architecture": "x64", "vhdGeneration": 2, "gallery": "<Example: myAzureComputeGallery>", "definition": "<Example: myImage1>", "version": "<Example: 1.0.1>" } } } Check Job Status & Test Results A job is an asynchronous operation that is updated throughout the job’s lifecycle with its operation and ongoing tests status. A job has 6 provisioning states – 4 are non-terminal states and 2 are terminal states. Non-terminal states represent ongoing operation stages and terminal states represent the status at completion. The job’s current state is reflected in the `properties.provisioningState` property located in the response body. The states are described below: Operation States State Type Description Accepted Non-Terminal state Initial ARM state describing the resource creation is being initialized. Queued Non-Terminal state The job has been queued by AITL to run LISA using the provided job template parameters.

How it works Infrastructure LISA is designed to be componentized and maximize compatibility with different distros. Test cases can focus only on test logic. Once test requirements (machines, CPU, memory, etc) are defined, just write the test logic without worrying about environment setup or stopping services on different distributions. Orchestration. LISA uses platform APIs to create, modify and delete VMs. For example, LISA uses Azure API to create VMs, run test cases, and delete VMs. During the test case running, LISA uses Azure API to collect serial log and can hot add/remove data disks. If other platforms implement the same serial log and data disk APIs, the test cases can run on the other platforms seamlessly. Ensure distro compatibility by abstracting over 100 commands in test cases, allowing focus on validation logic rather than distro compatibility. Pre-processing workflow assists in building the kernel on-the-fly, installing the kernel from package repositories, or modifying all test environments. Test matrix helps one run to test all. For example, one run can test different vm sizes on Azure, or different images, even different VM sizes and different images together. Anything is parameterizable, can be tested in a matrix. Customizable notifiers enable the saving of test results and files to any type of storage and database. Agentless and low dependency LISA operates test systems via SSH without requiring additional dependencies, ensuring compatibility with any system that supports SSH.

Linux Guest Image Validation: The quality team works with endorsed distribution partners for major releases to conduct thorough validation. Each refreshed image, including those from third-party publishers, is validated and certified before being added to the marketplace. Automated pipelines are in place to validate the images once they are available in the Marketplace. Package Validation: Unattended Update: We conduct validation of packages updates with target distro to prevent regression and ensure that only tested snapshots are utilized for updating Linux VM in Azure. Guest Extension Validation: Every Azure-provided extensions undergoes Basic Validation Testing (BVT) across all images and kernel versions to ensure compatibility and functionality amidst any changes. Additionally, comprehensive release testing is conducted for major releases to maintain reliability and compatibility. New VM SKU Validation: Any new VM SKU undergoes validation to confirm it supports Linux before its release to the Azure fleet. This process includes functionality, performance and stress testing across various Linux distributions, and compatibility tests with existing Linux images in the fleet. Azure HostOS & Host Agent Validation: Updates to the Azure Host OS & Agents are thoroughly tested from the Linux guest OS perspective to confirm that changes in the Azure host environment do not result in regressions in compatibility, performance, or stability for Linux VMs. At any stage where regressions or bugs are identified, we block those releases to ensure they never reach customers. All issues are resolved and rigorously retested before images, kernels, or extension updates are made available. Through these robust validation processes, Azure ensures that Linux VMs consistently deliver to customer expectations, delivering a reliable, secure, and high-performance environment for mission-critical workloads. Validation Tools for VM Guest Images and Kernel To ensure the quality and reliability of Linux VM images and kernels on Azure, we leverage open-source kernel testing frameworks like LTP, kselftest, and fstest, along with extensive Azure-specific test cases available in LISA, to comprehensively validate all aspects of the platforms.
