AIUI multicast between guests requires support in the router, which in
this case would be the host bridge device, eg. virbr0, or possibly

I have absolutely no idea if the Linux bridge device can do this though.

Do we have any test programs that can test this?  The only one I'm
aware of is udpcast.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
