(Aside: mDNS is blocked on some larger networks because it creates too
much load.  On those networks, an aggregator is essential - or a
protocol which scales better (less broadcasting)).

Doesn't libvirt use mDNS already to discover multiple hosts on a
network, for remote access?

If so, why can't exactly the same protocol be used to enumerate
multiple VMs on each host?

If not, why not?
