How are you attaching the guest network interface? Are you bridging it
to the host's physical ethernet adapter, or to a tap device? If you're
bridging to the physical interface, create a bridge on the host with
the physical network interface and a tap device, and bridge the guest
interface to the tap device. That might make a difference.
