Automating VMware to Hyper-V Migration with SCVMM
This blog post provides a PowerShell script for automating the migration of a virtual machine (VM) from most versions of VMware to Hyper-V using SCVMM 2022 UR2+ or 2025 and retaining all settings (yes, even the static IP!). With 10GB or better Layer 2 networking and flash storage, expected downtime is approximately 5 minutes per 100GB of disk.
Hyper-v Virtual Switch warning
We have a four nodes Windows 2025 Hyper-v cluster with only one virtual switch of 2 NICS On each node we get this warning repeatedly V-Switch operation IOCTL_SWITCH_GET_INFO_EX (2241648) took too long to complete. Operation Type: IOCTL. Execution time 0 ms. Queued time 0 ms. Expected execution time less than 0 ms. SwitchName: CF06EC90-20EB-460D-9A88-6820BFCCB14D. SwitchFriendlyName: SWPrincipale Searching for it didn't get any useful thread so far, has anyone seen it and found the cause ? thanks
Map vmdk to guest volume
I have a Hyper-V cluster and want PowerShell to give me a list of what vmdk file is assigned to which volume mount point in the virtual machine OS (Windows). Example: vmdk file mount point ------------------------------------------------------------------------------------------- C:\ClusterStorage\Data1\VM\ComputerA\Virtual Hard Disks\OSDisk.vhdx C:\ C:\ClusterStorage\Data1\VM\ComputerA\Virtual Hard Disks\MainMount.vhdx M:\ C:\ClusterStorage\Data1\VM\ComputerA\Virtual Hard Disks\Temp.vhdx M:\Temp The vmdks for C: and M: are mapped to drives in the guest, whereas Temp.vhdx is mounted in a folder under M:\. The main challenge for me is actually to find the correct elements that allow me to link a VMDK to a disk inside the virtual machine OS. The ones I found so far are: Get-Disk gives me numbers for adapter, port, target, and LUN, and Get-VMHardDiskDrive returns numbers for controller and location, which I guess link to target and LUN. But I'm pretty unsure whether it's safe to use these properties... Get-Disk returns a path, and I think I can use this to map the result of a win32_mountpoint CIM query to it to get the volume mount point... Does anyone have some valuable information for me on this?Windows Server on ARM64 (Insider Previews)
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.
Noob 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... JHyper-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?PowerShell 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...
RDP 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!Hyper-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 ? thanksStep-By-Step: Enabling Hyper-V for Use on Windows 11
