Hyper-V Virtual Machine Management service encountered an unexpected error: Logon

[Uber22]

Hey

 

I need to restore a vm from veeam but every time i do so i comes up with the following error he Hyper-V Virtual Machine Management service encountered an unexpected error: Logon failure: the user has not been granted the requested logon type at this computer.

 

i also cant create new VM machines, i know i can reboot the host but i wanted to see if anyone else has come across this issue.

 

Thanks

fixed by following this guide.

Hi,

The Group “NT Virtual Machine\Virtual Machines” is a special group. In Windows System there are certain special groups that are created by the system and that are used for special purposes.

I don’t find how to grant permission for these special groups, while I found a way to add these kinds of special groups to a normal group. So you can create a local group on the Hyper- V host, we name it “VMTest”. Then run below command to add the group “NT Virtual Machine\Virtual Machines” to “VMTest”.

Net localgroup VMTest “NT Virtual Machine\Virtual Machines” /add

After that, grant the “VMTest” group “Log on as a Service” user right.

Try this workaround and give us feedback for further troubleshooting.
