Customer Offerings: Hyper-V - Implementation, Migration, and Management
Happy April everyone! Brandon here, back once again to talk to you about a couple of new offerings that have just been released to assist our Unified customers with their on-premises virtualization needs! I continue to have the privilege of leading a great program and team helping customers to migrate from VMware to more cost-effective and/or modern solutions. These new offerings are <drum roll>: Hyper-V - Implementation, Migration, and Management Azure Local - Implementation, Migration, and Management NOTE: These offerings do not provide hands on keyboard support, do not create custom documentation for customers, and cannot provide direct support for any 3 rd party products that may be used in the process of migrations. Many customers are taking a closer look at Microsoft Hyper‑V as a strategic alternative to traditional virtualization platforms. Whether driven by changing licensing models, cost optimization, or the need for deeper hybrid cloud integration, a successful transition requires more than a technology shift—it requires a structured, outcome‑focused approach. While we are providing these new offerings to customers, you do also have the option of more extended engagements as well that are broader in scope and more tailored to the end goals while we work side by side with you. If you are a Unified customer and looking to move off of VMware to Hyper-V, or you just need help with your on-premises Microsoft virtualization technologies in general, have your account manager (CSAM) reach out to me! Planning to go at it alone?? I’m starting here for a very good reason… Virtually (no pun intended) every environment reviewed by my team (and that is a LOT) that was set up for a VMware migration, will have configuration issues, many times warranting a complete redesign and re-deployment. Problem 1: There are some potentially significant differences between the way VMware and Hyper-V are architected from the start, especially in areas of networking and storage, where mimicking methods used in the VMware world can actually lead to performance degradation in your target Hyper-V environment. Problem 2: To achieve feature parity, or near feature parity, your management method must also change. Additionally, if you are converting/migrating to Hyper-V, the available methods need to be determined, the terminology and functional differences identified and learned, well, honestly, I could go on for awhile on this, but I’ll spare you until we talk… Problem 3: Perhaps the most obvious is that this may be a new platform for your team, and its important for them to gain experience through guided actions and knowledge transfer on the fly for those questions they really have, which is exactly what we aim to provide in guiding implementations and migrations! You mentioned management and conversion tools, what do you mean?? Hyper‑V has several methods for management, which can vary based on the feature needs and environment size. As a simple example, if I have 1500 virtualization hosts and 30,000 virtual machines spread out globally, its probably not going to be as efficient to manage everything only through locally available consoles. The capabilities of these management methods are continuing to grow and improve based on customer feedback, along with feedback from the field team. Let’s take a quick look at these options: Native Windows tools: Hyper-V management console, Failover Clustering management console, Server Manager, etc This management method is typically used for small labs or smaller production environments (for migrations/conversions these methods do not provide feature parity with VMware). System Center Virtual Machine Manager (SCVMM) This management method is fully supported for environments of all sizes. For migrations/conversions this method provides feature parity with VMware for management and features, along with offering VMware migration/conversion capability (offline). If you are already using any product from the System Center suite (SCCM, SCOM, SCORCH, SCSM, or DPM) then this can prove to be a great no cost option for you! Windows Admin Center: Administration Mode (aMode) This management method is fully supported for environments of all sizes, however, is not designed as an infrastructure wide virtualization management method, but for server management and administration. If your environment isn’t extremely large, and VMware feature parity is not a necessity, this can provide a great no cost option for management of your physical and virtual servers. In addition, this method provides an online conversion option (currently public preview), allowing for a more seamless migration from VMware. Windows Admin Center: Virtualization Mode (vMode) (currently public preview) This management method is fully supported for environments of all sizes, and is designed solely for the purpose of managing the Hyper-V virtualization infrastructure, tying together the primary needs for virtualization fabric into an easy to navigate web-based UI. Azure You can Arc enable any Windows host or virtual machine and have a method of management and integration with cloud based services. In addition, these can work in conjunction with all of the above options to improve your management experience for your platform, and allows for the easy implementation and integration of many cloud based technologies (such as Hyper-V replica backups to ASR) NOTE: You can learn more about Windows Admin Center evolution here: Windows Admin Center Architectural Changes | Microsoft Community Hub A Structured Engagement Model Successful Hyper‑V implementations are built around a guided engagement model rather than a one‑size‑fits‑all checklist. Each engagement is tailored to the customer environment, acknowledging that differences in scale, workloads, hardware, and operational maturity directly influence the migration approach. The framework emphasizes collaboration, clarity of expectations, and incremental progress instead of disruptive “lift‑and‑shift” execution. Whether we are talking about a migration from another virtualization platform, or simply trying to reduce costs by implementing a new virtualization infrastructure, we’re here to help! Key Phases of a Hyper‑V Implementation and/or Migration Most Hyper‑V engagements progress through a common set of phases: Engagement scoping and technical discovery to understand goals and current state (this is the conversation I, or one of the TZ Leads in the VMware Migration Program have with customers) Planning and design aligned to business and operational outcomes, with a limited scope Deployment and configuration validation to ensure platform readiness Security and migration testing to reduce risk and confirm workload compatibility Optional feature enablement, including Azure Arc, to extend governance and management While these phases provide structure, the sequence and depth of each stage are adapted based on the customer environment and objectives. Key Outcomes for Customers Organizations that engage in Hyper-V implementation or migration efforts commonly achieve: Deeper familiarity with Microsoft virtualization technologies Successful deployment of PoC, pilot, or production environments Validated test migrations of virtual machines Identification and resolution of technical blockers Increased confidence in operational readiness These engagements are advisory and collaborative in nature, prioritizing customer enablement and success. Knowledge Transfer and Operational Readiness A central focus of a Hyper‑V engagement is ensuring that IT teams are prepared to operate the platform long after deployment completes. Knowledge transfer is embedded throughout the engagement through working sessions and direct participation in implementation activities. This approach helps organizations move confidently into steady‑state operations without relying on long‑term external support. As I mentioned above, if you do feel you will need longer term support, we have your back on that front as well. Looking Beyond Migration A Hyper‑V migration is often the first step in a broader transformation journey. Many organizations use this transition to enable hybrid management, strengthen security posture, and prepare for future application or cloud modernization initiatives. When approached strategically, Hyper‑V becomes a platform for long‑term innovation, not just a replacement hypervisor. Conclusion Moving from VMware to Hyper‑V is not simply a technical migration—it is an opportunity to modernize how infrastructure is managed and governed. With structured planning, guided execution, and a focus on operational readiness, organizations can transition with confidence to a virtualization platform built for today’s hybrid cloud realities and tomorrow’s growth. Thanks for reading, and maybe we’ll talk soon!
Creating Azure SQL VM with same name as VM
Hi, Currently we have a resource group, which contains a Virtual Machine and SQL Virtual Machine (and a few other resources). The VM and SQL VM has the same name: I want to move this resource group (and its resources) to another subscription. We tried using Resource Mover, but we couldn't as there are backups. I tried the steps in the following link: https://petri.com/copy-azure-vm-using-managed-disk-snapshots/ I was successful in moving 5 of the 6 resources to the new subscription, but was unable to move the SQL virtual machine: I tried to create a SQL virtual machine, but it says I can't create one with the same name: I found that in order to create a VM and SQL VM's with the same name, in the above image, I have to choose an image that has SQL Server and Windows. But this doesn't allow me to use the original managed disk (it only has an OS disk) and it also creates a couple of more disks, which are not in the original resource group. I was wondering if there are recommendations on how to create a SQL VM that has the same name as the VM in the same resource group and are also linked to each other. Jason
Network Monitoring
Hi, I recently applied Network Security Groups on Virtual Networks (NSG). Now my question is, is it possible to monitor / record the network traffic? For example, I've configured many rules on the NSG, now a application on a Server won't work and my first guess is the NSG is blocking the communication. How do I see now which port the application is using so I can set a new rule to the NSG? I know when you already know the port you can check it in Network Watcher "IP flow verify and NSG diagnostics" as a whatif state. Traffic Analytics isn't the right answer too or am I seeing it wrong? Vnet Flow Logs should be the right thing. I configured it, applied traffic analytics and a account storage. Applied it for testing on a nic but I don't see anything practical for my use? The only thing Iwish is to see live or logged the traffic if the NSG blocked anything and troubleshoot.Boosting Performance with the Latest Generations of Virtual Machines in Azure
Microsoft Azure recently announced the availability of the new generation of VMs (v6)—including the Dl/Dv6 (general purpose) and El/Ev6 (memory-optimized) series. These VMs are powered by the latest Intel Xeon processors and are engineered to deliver: Up to 30% higher per-core performance compared to previous generations. Greater scalability, with options of up to 128 vCPUs (Dv6) and 192 vCPUs (Ev6). Significant enhancements in CPU cache (up to 5× larger), memory bandwidth, and NVMe-enabled storage. Improved security with features like Intel® Total Memory Encryption (TME) and enhanced networking via the new Microsoft Azure Network Adaptor (MANA). By Microsoft Evaluated Virtual Machines and Geekbench Results The table below summarizes the configuration and Geekbench results for the two VMs we tested. VM1 represents a previous-generation machine with more vCPUs and memory, while VM2 is from the new Dld e6 series, showing superior performance despite having fewer vCPUs. VM1 features VM1 - D16S V5 (16 Vcpus - 64GB RAM) VM1 - D16S V5 (16 Vcpus - 64GB RAM) VM2 features VM2 - D16ls v6 (16 Vcpus - 32GB RAM) VM2 - D16ls v6 (16 Vcpus - 32GB RAM) Key Observations: Single-Core Performance: VM2 scores 2013 compared to VM1’s 1570, a 28.2% improvement. This demonstrates that even with half the vCPUs, the new Dld e6 series provides significantly better performance per core. Multi-Core Performance: Despite having fewer cores, VM2 achieves a multi-core score of 12,566 versus 9,454 for VM1, showing a 32.9% increase in performance. VM 1 VM 2 Enhanced Throughput in Specific Workloads: File Compression: 1909 MB/s (VM2) vs. 1654 MB/s (VM1) – a 15.4% improvement. Object Detection: 2851 images/s (VM2) vs. 1592 images/s (VM1) – a remarkable 79.2% improvement. Ray Tracing: 1798 Kpixels/s (VM2) vs. 1512 Kpixels/s (VM1) – an 18.9% boost. These results reflect the significant advancements enabled by the new generation of Intel processors. Score VM 1 VM 1 VM 1 Score VM 2 VM 2 VM 2 Evolution of Hardware in Azure: From Ice Lake-SP to Emerald Rapids Technical Specifications of the Processors Evaluated Understanding the dramatic performance improvements begins with a look at the processor specifications: Intel Xeon Platinum 8370C (Ice Lake-SP) Architecture: Ice Lake-SP Base Frequency: 2.79 GHz Max Frequency: 3.5 GHz L3 Cache: 48 MB Supported Instructions: AVX-512, VNNI, DL Boost VM 1 Intel Xeon Platinum 8573C (Emerald Rapids) Architecture: Emerald Rapids Base Frequency: 2.3 GHz Max Frequency: 4.2 GHz L3 Cache: 260 MB Supported Instructions: AVX-512, AMX, VNNI, DL Boost VM 2 Impact on Performance Cache Size Increase: The jump from 48 MB to 260 MB of L3 cache is a key factor. A larger cache reduces dependency on RAM accesses, thereby lowering latency and significantly boosting performance in memory-intensive workloads such as AI, big data, and scientific simulations. Enhanced Frequency Dynamics: While the base frequency of the Emerald Rapids processor is slightly lower, its higher maximum frequency (4.2 GHz vs. 3.5 GHz) means that under load, performance-critical tasks can benefit from this burst capability. Advanced Instruction Support: The introduction of AMX (Advanced Matrix Extensions) in Emerald Rapids, along with the robust AVX-512 support, optimizes the execution of complex mathematical and AI workloads. Efficiency Gains: These processors also offer improved energy efficiency, reducing the energy consumed per compute unit. This efficiency translates into lower operational costs and a more sustainable cloud environment. Beyond Our Tests: Overview of the New v6 Series While our tests focused on the Dld e6 series, Azure’s new v6 generation includes several families designed for different workloads: 1. Dlsv6 and Dldsv6-series Segment: General purpose with NVMe local storage (where applicable) vCPUs Range: 2 – 128 Memory: 4 – 256 GiB Local Disk: Up to 7,040 GiB (Dldsv6) Highlights: 5× increased CPU cache (up to 300 MB) and higher network bandwidth (up to 54 Gbps) 2.

Hi, I am provisioning VMs as session hosts for AVD, using Entra ID for login. During the deployment process, one of the resources is Microsoft.Compute/virtualMachines/extensions/Microsoft.PowerShell.DSC. Based on the deployment information, the artifacts (scripts) that are being used come from this path: https://wvdportalstorageblob.blob.core.windows.net/galleryartifacts/Configuration_1.0.02893.601.zip The confusing part is that when I view those files, they are a bit different than the ones stored in the Azure GitHub repo here: https://github.com/Azure/RDS-Templates/tree/master/ARM-wvd-templates/DSC Is the GitHub repo just out of date or need review? I have questions on the implementation of the scripts, but it seems like figuring this out is the necessary first step.
Determining sizing requirements for GPU enabled Azure VM
Greetings, We are trying to determine the correct VM sizing requirement for our AI workload, which is used for NLP processing. This workload does not require any training, but will only be used for inference. We have the following software configuration: a C# application that is heavily multithreaded using a lot of socket I/O. The application has concentrated bursts where 10-20 threads are fired concurrently to perform tasks (mostly socket I/O). This app communicates via dedicated sockets to: a Python application which performs various NLP tasks. This app is also multithreaded to handle multiple incoming requests from the .NET app. This app sends queries to a local LLM (model size will vary based on query type). We estimate we will need to support sub-second performance (at the very least) on a 7B parameter model. Ultimately, we may need to go to larger model sizes if accuracy is insufficient. The amount of text passed to the LLM will range from 300-3000 tokens. In short, we need: a) a CPU with sufficient cores to handle multiple concurrent threads on the .NET side. The app will have 5 or 6 background threads running continuously, and sudden bursts of activity which will require a minimum of 10-20 threads to run shorter-lived tasks. b) a GPU with sufficient VRAM to handle at the very least, a 7B parameter model. Ultimately, we may need to support larger models to perform the same task due to insufficient accuracy. We need the ideal configuration of GPU/VRAM and CPU/RAM to handle these tasks, and also, potentially, larger LLM sizes of up to 14B or 70B parameters. We are looking at the NC-series VMs, with a budget of about $1,000/month (see https://learn.microsoft.com/en-us/answers/questions/2150959/determining-sizing-requirements-for-gpu-enabled-az?comment=question). Any feedback on the optimal configuration in terms of CPU/GPU would be greatly appreciated. Thank you in advance.
Adding VM Instance View Details, e.g. osName, to the VM Resource Object JSON (for Custom Policy Use)
I'm requesting to add more details to the JSON of the VM resource object, particularly from the VM instance view data. This is to include operating system information, such as the name and version (osName and osVersion), for use in a custom Policy. Although these details are visible in the portal, they're not present in the VM's resource object, which is necessary for our custom policy.
Automating Azure VM Snapshot Creation Across Subscriptions
Introduction Managing virtual machines in Azure can be time-consuming, especially when creating snapshots across multiple subscriptions. Typically, this involves logging into the Azure portal, manually locating the VM, and creating snapshots for both the OS disk and attached data disks an inefficient and tedious process. To simplify this, I developed a PowerShell script that automates snapshot creation, allowing me to create snapshots by simply inputting the VM name. This script is part of my toolkit for automating repetitive Azure tasks. It iterates through all subscriptions linked to my Azure account, identifies the specified VM, and generates snapshots for both the OS and data disks within the VM’s resource group, adhering to a consistent naming convention. This article describes the script, the rationale behind its design, and how it improves the efficiency of managing Azure resources. Design Considerations When designing this script for automating Azure VM snapshot creation, several key considerations were prioritized to enhance efficiency and user experience: 1. Subscription Handling All-Subscription Search: The script loops through all Azure subscriptions associated with the account. This design ensures that the script can locate the VM across any subscription without manual intervention to switch between them. This is particularly useful for environments with multiple subscriptions. 2. Dynamic VM Search Automatic VM Discovery: Instead of requiring users to manually input resource group and subscription details, the script dynamically searches for the VM by its name across all subscriptions. This automation simplifies the process and reduces the likelihood of errors. 3. Snapshot Naming Convention Consistent Naming Format: Snapshots are named using the format VMname_diskname_dd-MM-yyyy_HH_mm. This approach ensures that snapshots are well-organized and easily identifiable. The script also removes random characters, such as GUIDs, often appended to disk names, resulting in clean and consistent snapshot names. 4. OS and Data Disk Snapshots Comprehensive Backup: The script separately handles snapshots for both the OS disk and data disks. This ensures that all disks attached to the VM are included in the backup process, providing complete coverage. 5. Time Efficiency Streamlined Process: The script is designed to eliminate the need for repeated manual input and navigation within the Azure portal. By simply providing the VM name, users can automate the entire process, from VM identification to snapshot creation. This saves considerable time and effort, particularly in environments with many VMs and subscriptions. By focusing on these design considerations, the script offers a robust and user-friendly solution for automating VM snapshot creation across Azure subscriptions. Prerequisites To use this script, you need: Azure PowerShell module installed (Az module). Active Azure account with sufficient permissions to access VMs and create snapshots across subscriptions. A VM name as input. Why Automate Snapshot Creation? In many organizations, virtual machines (VMs) are critical for running services, and regularly creating snapshots of these VMs is essential for disaster recovery and version control. Traditionally, creating snapshots for Azure VMs involves several manual steps: Log in to the Azure Portal: Access the Azure portal to start the snapshot creation process. Navigate Through Subscriptions: Switch between different Azure subscriptions to find the correct VM. Locate the Correct VM: Search for and select the specific VM for which you want to create snapshots. Create Snapshots: Manually create snapshots for both the OS disk and any attached data disks. Repeat the Process: Perform these steps for each disk across multiple VMs or subscriptions. This manual process is not only time-consuming but also prone to errors. Automating snapshot creation simplifies and streamlines the process: Reduces Manual Effort: The entire process can be accomplished with a few clicks. Saves Time: Automation eliminates the need to repeat steps across multiple VMs and subscriptions. Minimizes Errors: By automating the process, you reduce the risk of human error. With the automation script, you only need to provide the VM name, and the script handles the rest, making snapshot management more efficient and reliable. Script Overview Below is the PowerShell script that automates the process of creating snapshots for a VM across multiple subscriptions in Azure: <# .SYNOPSIS This script automates the process of creating snapshots for a virtual machine (VM) in Azure across multiple subscriptions. The script will locate the VM by its name, determine the resource group where it exists, and create snapshots for both the OS disk and any attached data disks. It ensures that the snapshot names follow a specific naming convention while removing any random characters appended to the disk names. .DESCRIPTION - Loops through all Azure subscriptions attached to the account. - Searches for a specified VM by name across all subscriptions. - Identifies the resource group of the VM. - Creates snapshots for the OS disk and all data disks in the same resource group as the VM. - Follows the snapshot naming convention: computername_diskname_dd-mm-yyyy_hh_mm. - Removes random characters (e.g., GUIDs) after the disk name in snapshot naming. .NOTES Author: Vivek Chandran Date Created: 11-09-2023 #> # Login to Azure (if not already logged in) Connect-AzAccount # Prompt the user to enter the VM name $computerName = Read-Host -Prompt "Please enter the name of the VM you want to snapshot" # Get all subscriptions available to the account $subscriptions = Get-AzSubscription # Loop through each subscription to find the specified VM foreach ($subscription in $subscriptions) { # Set the subscription context so that all subsequent commands target this subscription Set-AzContext -SubscriptionId $subscription.Id # Retrieve all VMs in the current subscription $vms = Get-AzVM # Check if a VM with the specified name exists in this subscription $vm = $vms | Where-Object { $_.Name -eq $computerName } if ($vm) { # Output message indicating the VM was found Write-Host "VM '$computerName' found in subscription '$($subscription.Name)'" # Retrieve the resource group where the VM resides $resourceGroup = $vm.ResourceGroupName # Loop through each data disk attached to the VM and create a snapshot foreach ($disk in $vm.StorageProfile.DataDisks) { # Get the name of the data disk $diskName = $disk.Name # Remove any random characters from the disk name after the first underscore (if present) $cleanedDiskName = ($diskName -split '_')[0..1] -join '_' # Get the current date and time in the format 'dd-MM-yyyy_HH_mm' for use in the snapshot name $currentDateTime = Get-Date -Format 'dd-MM-yyyy_HH_mm' # Construct the snapshot name using the cleaned disk name and the date/time $snapshotNameWithDataDisk = "$computerName-$cleanedDiskName-$currentDateTime" # Define the snapshot configuration using the disk's managed disk ID $snapshotConfig = New-AzSnapshotConfig -SourceUri $disk.ManagedDisk.Id -Location $vm.Location -CreateOption Copy -AccountType Standard_LRS # Create the snapshot in the same resource group as the VM New-AzSnapshot -Snapshot $snapshotConfig -ResourceGroupName $resourceGroup -SnapshotName $snapshotNameWithDataDisk # Output message indicating that the snapshot was successfully created for the data disk Write-Host "Snapshot created for data disk: $snapshotNameWithDataDisk" } # Create a snapshot for the OS disk of the VM $osDisk = $vm.StorageProfile.OsDisk # Get the name of the OS disk $osDiskName = $osDisk.Name # Remove any random characters from the OS disk name after the first underscore (if present) $cleanedOsDiskName = ($osDiskName -split '_')[0..1] -join '_' # Get the current date and time in the format 'dd-MM-yyyy_HH_mm' for use in the snapshot name $currentDateTime = Get-Date -Format 'dd-MM-yyyy_HH_mm' # Construct the snapshot name using the cleaned OS disk name and the date/time $snapshotNameWithOSDisk = "$computerName-$cleanedOsDiskName-$currentDateTime" # Define the snapshot configuration using the OS disk's managed disk ID $snapshotConfig = New-AzSnapshotConfig -SourceUri $osDisk.ManagedDisk.Id -Location $vm.Location -CreateOption Copy -AccountType Standard_LRS # Create the snapshot in the same resource group as the VM New-AzSnapshot -Snapshot $snapshotConfig -ResourceGroupName $resourceGroup -SnapshotName $snapshotNameWithOSDisk # Output message indicating that the snapshot was successfully created for the OS disk Write-Host "Snapshot created for OS disk: $snapshotNameWithOSDisk" # Exit the loop since the VM has been found and processed break } else { # Output message indicating that the VM was not found in this subscription Write-Host "VM '$computerName' not found in subscription '$($subscription.Name)'" } } # Output a final message indicating that the snapshot process has completed Write-Host "Snapshots process completed!" How the Script Works 1. Azure Authentication Connect to Azure: The script starts by authenticating the user to Azure using the Connect-AzAccount command. If the user is already logged in, this step is skipped. 2. Input the VM Name Prompt for VM Name: After successful authentication, the script prompts you to enter the name of the virtual machine (VM) you want to create snapshots for. 3. Subscription Looping Retrieve Subscriptions: The script retrieves all Azure subscriptions associated with the account using Get-AzSubscription. Check Each Subscription: It iterates through each subscription to check if the specified VM exists. When the VM is found, the script switches the context to that subscription using Set-AzContext. 4. Snapshot Creation Data Disk Snapshots: For each data disk attached to the VM, the script creates a snapshot. It follows a consistent naming convention that includes the VM name, disk name, and timestamp to ensure clarity and organization. OS Disk Snapshot: After handling the data disks, the script creates a snapshot for the OS disk, using the same naming convention. 5. Completion Confirmation Message: Once all snapshots (for both OS and data disks) are created, the script outputs a message confirming the successful completion of the snapshot creation process. Conclusion This PowerShell script has greatly improved my workflow for managing Azure VMs. By automating the snapshot creation process, it eliminates the need to manually log into the Azure portal, locate the VM, and create snapshots for each disk individually. Instead, I can simply run the script, provide the VM name, and let it handle the entire process. For anyone managing multiple Azure subscriptions and seeking a reliable method to automate snapshot creation, this script offers a quick and effective solution. It ensures that backups are created consistently and stored properly, enhancing overall backup management and efficiency.
