As explained above you can't run x86 Guest OS w/ above Hypervisors.

You can use the qemu/crosvm w/ above Hypervisors to do the ARM64
guest OS. You may be able to use Pixel device as well w/ the pKVM. 

I also suggest that you don't do the "reactions" with gmail. It 
doesn't help this conversation. 

Let us know what exactly you would like to experiment with above
Hypervisors.
