When will there be a preview build of Windows Server on ARM? There is demand for it from developers, and devops personal as well. It is known that it already partial exists due to the article on Azure Host OS. Azure Host OS – Cloud Host - Microsoft Community Hub Please release this so we can test it against our code.44KViews9likes23CommentsNoob needs help with RDP Services
I am new to Windows server management. I setup a 2019 Server in a VM (Hyper-V). I installed the licenses we got for RDP from MS after installing the Remote Desktop Services. I am getting an error about Remote Desktop Licensing Mode is not configured. Tells me to use Server Manger to specify RD Connection Broker. Either I neglected to install it or configure it, not sure. Articles I find say go to Server Manager -> Remote Desktop Services -> Overview... BUT, that tells me I am logged in with a local account but must use a domain account to manage servers and collections. Again, not using a DC. This server is not part of a domain. We do not run AD internally only AzureAD online. We have 1 program we still run internally and users RDP to it. Should I remove the service and reinstall? What about the licenses I added already? How to I keep them? Any assistance will be greatly appreciated... J77Views0likes2CommentsHyper-V: How do VMs communicate with external?
Simple scenario: VM --> vNIC --> vSwitch (external) --> physNIC --> physSwitch The vNIC assigned to the VM has MAC address aa:aa:aa:aa:aa:aa, the physical NIC (physNIC; the vSwitch of type external is connected to it) has bb:bb:bb:bb:bb:bb. What mechanism ensures that when the VM sends a network packet to the external network (the physical network connected to the physical switch physSwitch), the MAC address of its vNIC (aa:aa:aa:aa:aa:aa) is used, and not the MAC address of the physNIC (bb:bb:bb:bb:bb:bb)? In other words: what makes physSwitch "see" aa:aa:aa:aa:aa:aa when the VM communicates to an external endpoint?92Views0likes1CommentPowerShell counterpart for Failover Cluster Manager "Live Migration Settings"
In Failover Cluster Manager, there's "Live Migration Settings" where I can define what cluster networks I want to carry live migration traffic. Even after some research, I cannot find a PowerShell cmdlet that lets me do the same...90Views0likes1CommentRDP connection not possible and RDS-Virtualization role comes back after restart
Hello everyone, I have here an Windows Server 2022 Standard 21H2 (Build 20348.4052) (essentials) with the newest updates. This is the Domain Controller. Hyper-V is installed with one VM. The VM is a terminal server. In the past I have tried to install the terminal server on the Hyper-V Server. To do so I have installed all kind of remotdesktop roles. This was stupid of me. Especially it does not work on a DC. I want to connect as administrator by RDP (mstsc) to the server but it does not work anymore since I have installed all these roles and features. No other users are connected. I can still connect to the VM. In one situation I was able to connect to the server but after entering the password I have received the error 0x808 (0x101) that there is no licence server for remote desktop available. I have now removed all roles related to the terminal server and the rdp which I have installed. But I can not uninstall RDS-Virtualization. After uninstalling it comes back when I perform a restart. I have already tried Uninstall-WindowsFeature -Name RDS-Virtualization -Remove In the server manager appears a menu item about remote desktop services. But there is written that no connection broker server is in the pool. The submenu server lists my DC. I have found in the eventmanager a error related to the uninstalling process 0x80070057 wrong parameter But I do not have more information. DISM /RestoreHealth and sfc /scannow did not find any problems. I am not using VDI but is maybe the Hyper-V reinstalling the role after the restart? Do I need to uninstall the role to make RDP working again or could be there other reasons? Do you know where I find a detailed log about the problems about uninstalling the role and maybe the installing? Do you have any idea how I can find out more about the problem? Thank you!68Views0likes1CommentHyper-v Replica Traffic segregation
We have two standalone Windows 2025 Hyper-v Servers. They have been configured with a network team for Management, one for VM traffic and one for replica traffic. We have configured both hosts with self-signed certificate to configure HTTPS replica. The two hosts FQDN are host1.company.com host2.company.com and those names are resolved in the DNS with the management Network IP. To have the replica going through the "replica team" we created on each host's host file two entry like host1.repl.company.com host2.repl.company.com pointing to the replica network IP. The self-signed certificate of each host contains both fqdn ( xxx.company.com, xxx.repl.company.com ) Problem is that when activating a replica for a VM if we chose xxx.repl.company.com as replication partner the process fails with the error that the hosts cannot be contacted, if we use the fqdn company.com it works. To test connectivity we also set the hosts file using the replica network IP for the company.com FQDN and it works. So it's like it doesn't like the FQDN repl.company.,com Any Idea on what the issue might be ? thanks44Views0likes1CommentStep-By-Step: Enabling Hyper-V for Use on Windows 11
Want to use Hyper-V on Windows 11? Hyper-V is a virtualization technology that is valuable not only for developers and IT Professionals, but also for college and university students. This step-by-step guide will show you how to enable Hyper-V on your Windows 11 machine.1.3MViews12likes36CommentsUnable to personalize display in Hyper-V VM
I have two physical servers running Windows Server 2025 Standard Edition, each with Hyper-V installed. On the first 2025 server, I have no issues adjusting video/personalization settings in running virtual machines. On the second server, I created a 2025 domain controller but I am unable to adjust any of the video settings ("remote resolution changes not allowed") even though enhanced sessions are enabled. How can I fix this on the second server? Thanks.38Views0likes0CommentsvNVMe on Hyper-V to unlock PCIe 5.0 NVMe performance
On hosts with NVMe PCIe 5.0 (E3.S/U.2), Hyper-V guests still use virtual SCSI and leave a lot of performance on the table. We are paying for top-tier storage, yet software becomes the limiter. A virtual NVMe device that preserves checkpoints/Replica/Live Migration would align guest performance with modern hardware without forcing DDA and its operational trade-offs.353Views1like6CommentsEnable Nested Virtualization on Windows Server 2025
Nested virtualization allows you to run Hyper-V inside a VM, opening up incredible flexibility for testing complex infrastructure setups, demos, or learning environments, all without extra hardware. First, ensure you’re running a Hyper-V host capable of nested virtualization and have the Windows Server 2025 VM on which you want to enable as a Hyper-V host ready. To get started, open a PowerShell window on your Hyper-V host and execute: Set-VMProcessor -VMName "<Your-VM-Name>" -ExposeVirtualizationExtensions $true Replace <Your-VM-Name> with the actual name of your VM. This command configures Hyper-V to allow nested virtualization on the target VM. Boot up the Windows Server 2025 VM that you want to configure as a Hyper-V host. In the VM, open Server Manager and attempt to install the Hyper-V role via Add Roles and Features. Most of the time, this should work right away. However in some cases you might hit an error stating: “Hyper-V cannot be installed because virtualization support is not enabled in the BIOS.” To resolve this error run an elevated PowerShell session inside the VM on which you want to enable Hyper-V and run the command: bcdedit /set hypervisorlaunchtype auto This command ensures the Hyper-V hypervisor starts up correctly the next time you boot. Restart your VM to apply the change. After the reboot, head back to Add Roles and Features and try installing Hyper-V again. This time, it should proceed smoothly without the BIOS virtualization error. Once Hyper-V is installed, perform a final reboot if prompted. Open Hyper-V Manager inside your VM and you’re now ready to run test VMs in your nested environment!306Views1like0Comments
