I just tried it and yes it is possible. On the 2nd screen where it asks 
for IPv4 info, just uncheck the "Enable IPv4" checkbox, then on screen 
4, clear out the "DNS Domain Name" at the bottom of the page. This will 
give you a virtual network with a bridge created by libvirt, but no IP 
address on the bridge itself, so no traffic will be able to go to/from 
the host from that bridge. The only other bit you'll need to do is setup 
the dhcp server on the router guest.
