Just adding that virtualbox 6 works(ish) [1] with hyper-v thanks to the use of the virtualization API [2] to setup the VM.

AFAIK that does not like VirtualBox 6 works with Hyper-V but it's like running Hyper-V instead of VirtualBox. Therefore there is a lot of compatibility issue.

This is how hypervisor nesting works, a lot of issues, trust me.
