I'm not able to Start any VMs in VirtualBox and getting this error:
Cannot enable nested VT-x/AMD-V without nested-paging and unrestricted
guest execution! (VERR_CPUM_INVALID_HWVIRT_CONFIG).
I reinstalled latest VirtualBox and was same issue still exist.
Note that recently I did WSL2 installation by the following this official documentations so I thought the problem should be related to this installation, and decided to rollback some steps (not Uninstall WSL2 itself) to verify;
After all I found that "Step3: Enable Virtual MachinePlatform feature" was causing this problem:
Before installing WSL 2, you must enable the Virtual Machine Platform
Open PowerShell as Administrator and run:
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
Restart your machine to complete the WSL install and
update to WSL 2.
So I removed this feature and VM Start problem resolved, but after that WSL2 doesn't start now.
Now I'm stuck here what to do, I need both WSL & VMs to working while they are not happy with that feature to Disable or Enable for both.
