I'm using this setup with KVM virtualization (Qemu's successor). It
didn't work with default nic type for guest (realtek I think) as 802.1q
tags were not preserved properly in one of the directions. I don't
remember specifics. Anyway using e1000 driver instead of default fixed
it. Works like a charm.
