Usually vsock tests test both the driver (virtio-vsock) in the guest and 
the device in the host kernel (vhost-vsock). So I usually run the tests 
in 2 nested VMs to test the latest changes for both the guest and the 
host.

I don't know enough selftests, but do you think it is possible to 
integrate them?

CCing Stefan who is the original author and may remember more reasons 
about this choice.
