Hmm, assuming we're both looking at the same diagram, I think your interpretation is wrong. Figure 18.4 (under section 18.3.1) is showing one virtual network (192.168.122.0/24) with two guests attached to it. I don't see any examples there which describe setup for 2 virtual networks. > 2. was playing around "Network teaming" in a VM. But this > doesnt seem to work. Please dont beat me around the use > cases for this :) Ok, so the virtual network NAT feature in libvirt doesn't include network teaming directly. The NAT based setup you've got in the XML causes libvirt to create a linux software bridge and connect guest TAP devices to that. Note that no physical network is enslaved in that bridge - only guest NICs. Traffic from the bridge to the LAN is forwarded at the IP level. So if your host has been configured with bonding, eg you have eth0 and eth1 configured into bond0 and have setup your hosts public IP on bond0, then the NAT routing should automatically go to bond0. So don't think creating multiple virtual networks really does anything useful for network teaming. ie If you've setup your host OS with bonding, then a single libvirt virtual network should suffice.
