Hyper-V Move VMs from one Host in DomainA to another Host in DomainB

Hi,

We are migrating between domains. Part of this is moving VMs from one host on DomainA to another host on DomainB. We currently have CredSSP enabled for Hyper-V Live Migration on all hosts.

We're getting this error message back from the target Hyper-V host, when attempting the move on the source Hyper-V host:

We have followed this guide https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/manage/remotely-manage-hyper-v-hosts, specifically the Connect to a Windows Server 2016 or Windows 10 remote host outside your domain, or with no domain section with no luck. We also made sure Windows Firewall is disabled everywhere, and tried adding the source Hyper-V host to the local Administrators, Hyper-V Administrators, and Remote Management Users groups on the target Hyper-V host.

Running out of ideas!

Thanks

    Hi there,

    You can try the below steps and see if that sorts the issue.

    -Open "Window Security"
    -Open "App & Browser control"
    -Click "Exploit protection settings" at the bottom
    -Switch to "Program settings" tab
    -Locate "C:\WINDOWS\System32\vmcompute.exe" in the list and expand it
    -Click "Edit"
    -Scroll down to "Code flow guard (CFG)" and uncheck "Override system settings"
    -Start vmcompute from powershell as administrator net start vmcompute
    -Restart
    -Start Hyper-V Manager as administrator

    The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue. https:// social.technet.microsoft.com/Forums/windows/en-US/e245681e-e4dd-44c2-9b9e-26a5df1f473c/check-that-the-virtual-machine-management-service-is-running-and-that-you-are-authorized-to-connect?forum=w8itprovirt
