This patch looks good to me.

I did some quick tests with the 13 patches in a Linux VM (this is not
a nested VM) on Hyper-V and it looks nothing is broken. :-)

> I'll try to setup a Windows host where to test the nested VMs

I suppose you're going to run a Linux VM on a Hyper-V host,
and the Linux VM itself runs KVM/VmWare so it can create its own child 
VMs. IMO this is similar to the test "nested KVM ( ..., virtio-transport[L1,L2]"
you have done.
.
Thanks!
