wsl: Nested virtualization is not supported on this machine.

Note

These WSL error messages occur from time to time and can tricky to troubleshoot short of reinstalling WSL.

They are usually not an issue with WLinux itself but a glitch with the underlying Windows Subsystem for Linux in Windows 10.

You can help us help you and Microsoft improve WSL and address these if you can provide us some debugging information.

[ ] I have read the above statement.

Basic Troubleshooting

Please check:

[ ] I have confirmed WSL is enabled: https://docs.microsoft.com/en-us/windows/wsl/troubleshooting#confirm-wsl-is-enabled. [ ] I have searched Google for the error message. [ ] I have searched the official Microsoft WSL issues page: https://github.com/Microsoft/WSL/issues. [ ] I have searched the WLinux issues page: https://github.com/WhitewaterFoundry/WLinux/issues. [ ] I have reset WLinux: Settings->Apps->Apps & features->WLinux->Advanced Options->Reset. [ ] I have disabled and re-enabled WSL in Windows Features. [ ] I have run Windows 10 updates and restarted.

What other troubleshooting have you attempted to date?

i think it s just a warning that distro itself cannot do nested virtualization

Hello,

It is not the distro it is your processor. Do you have an AMD processor with Windows 10?

The warning is only shown on the first distro that you launch. You can get rid of this warning disabling the nested virtualization on WSL with:

echo -e "\n[wsl2]\nnestedVirtualization=false\n" >>winhome/.wslconfig

I was getting the warning on a playground Windows11 VM running on VMware Workstation with nested virtualization enabled ("Virtualize Intel VT-x/EPT or AMD-V/RVI) and Virtual Machine Platform (VMP) feature installed. I have AMD CPU with SVM enabled in bios.

Now, after I figured out how to set up WSL, I managed to install it directly on my main PC OS - Windows 11 with Virtual Machine Platform (VMP) enabled and here I do not get the warning.

I did not have a .wslconfig created in both cases, but on https://learn.microsoft.com/en-us/windows/wsl/wsl-config I see nestedVirtualization is enabled by default.

Now I am curious if that was just a warning or it was actually not working. Is there a way to easilly test nestedVirtualization actually works or not?

When you see the warning is because is not working. But I don't know why it isn't working with the VMware Workstation
