I am trying to create a separate private network between the host (domain 0) and the guests. Using virsh, I created a bridge network, virbr1. I can successfully add guest interfaces to the bridge network and communicate between the guests. However, I am unable to communicate between the host and any of the guests. I created eth0:1 on the host and configured virbr1 to forward to eth0:1 (mode=”route” dev=”eth0:1”), but there is still no communication.

I don’t think creating eth0:1 is the right thing to do. I think I need to create a virtual interface on domain 0 that is part of the bridge network, virbr1. However, when I run virsh attach-interface with domain-0, it fails.

What am I missing??
