Strange, I’ve setup dozens of virtualization clusters, and never used anything 
other than bridged networking.  I haven’t really met anyone using routed or NAT 
mode, but I guess there’s a first time for everything.

You might be able to get the NAT mode to work for you, to pass traffic between 
the networks, you probably only need to enable IP forwarding on the KVM host, 
and make sure the FORWARD chain in iptables accepts the packets.
