I currently have two vm's both on kvm (virt-manager), both running on separate virtual interfaces (virbr0 and virbr1). The IP of virbr0 is 192.168.122.0; the IP of virbr1 is 192.168.123.0. Both VMs can talk to each other. I am trying to make all traffic go through the VM on virbr0 (122.0) before going to virbr1 (123.0) from the host machine. Deleting the routing table for 123.0 and adding a new entry with the 122.0 VM as a gateway does not work, and the VMs lose connection after the route is deleted. Any ideas how the traffic can be forwarded to 122.0 before hitting 123.0?
