Recently I use upgraded both my mini pc to Windows 11. Everything running smoothly including Vmware Workstation with a few VMs running. However, I found an issue when want to run nested virtualization - Hyper-V.
"Virtualized AMD-V/RVI is not supported on this platform"
Here is my tweak to make it work:
1. Uninstall Windows Hypervisor Platform
Go to Control Panel | Programs and Features | Click Turn Windows features on or off
Uncheck the Windows Hypervisor Platform
2. Edit Local Group Policy
Type mmc | Add Group Policy Object | Local Computer
Go to Computer Configuration | Administrative Templates | System | Device Guard | Click on Turn on virtualization Based security | Set to Disable
Then restart your machine and test run nested virtualization.
That should do the trick!
