Patch 9 changes the hvs_remote_addr_init(). setting the
VMADDR_CID_HOST as remote CID instead of VMADDR_CID_ANY to make
the choice of transport to be used work properly.
@Dexuan Could this change break anything?

This patch looks good to me.

@Dexuan please can you test on HyperV that I didn't break anything
even without nested VMs?

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!
