Your two bridge addresses are in different subnets. If the IP you assign in your domu is in the 192.168.122 range, it won't be able to talk to anything on the 192.168.12 range.

Unless and untill you enable ip forwarding in Dom0. Once you enable ip forwarding, you would be able to communicate with another network. SNAT/MASQUERADE rule is automatically added by libvirt for you.
