Is it unable to use WSL 2 inside Hyper-V VM?

Question

I'm now using Windows 10 Pro build 20251 in my Hyper-V VM. I just tried this to use native GUI support on WSL, but I have constant installation errors on Linux. I've finished enabling WSL 2, tried both Ubuntu LTS 20.04 and Debian and failed.

Answer 1

Hi,
I could not confirm if Win 10 build 20251 will support WSL 2. Because Windows 10 Insider Preview Build was recently released. We haven't update to this version. But based on my check, there is no known issues about WSL. My Win10 2004 version will work fine.
WSL 2 uses a subset of Hyper-V for virtualization. So according to the error 0x80370102, we could check the virtualization setting has been enabled. If you're inside a Virtual Machine, your VM may not be setup to run nested VM. Please check the three steps in the link below:

After checking the three options, disabling Virtual Machine Platform, Windows Hypervisor Platform and Windows Subsystem for Linux in the "Turn Windows features off and on" and the rebooting, re-enabling and rebooting again.
Hope this helps and please help to accept as Answer if the response is useful.
Best Regards,
Carl
