[Windows 10 VM Now Suddenly Slow]

So it seems that nested virtualization was causing problems in my case.  I reenabled WSL but left off Hyper-V and Windows Hypervisor Platform and everything is running normally.  Interestingly, turning off Hyper-V in the Unraid VM settings did nothing to resolve the issue.  I needed to disable virtualization features inside Windows itself.

 

 

 

Yes Sir, this solved my bad VM-performence aswell. But i had the problem with deactivate the hyper-v. If this happen, use this command in prompt as Administrator. bcdedit /set hypervisorlaunchtype off

Hi,

I have the same probs with that. Unraid 6.8.3. All Vm´s that switched from or to GPU Passthrough to VNC back have the problems. I find out that after switching the Grafik output the "bus" from  0x00 chnaged to 0x07. With these settings the vms dosen´t work. After change the bus back to 0x00 the vm works fine. If the bus 0x00 is occupied, change the slot to 2 or 3. Sorry for my bad english :-) <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/>
