Subject Re: [Discuss] Getting rid of the Virtual Router (associated downtime)

That'd be an interesting approach, I do something similar on my vanilla libvirt installs.
This opens up some issues though, that of the HA of dnsmasq for one. It'd still be an interesting
idea, though and would very much play ball with the network filtering bits.

Cheers for sharing Wido
