I set the second one manually; copied the first one and added one.

vif = [ "mac=00:16:3e:5b:44:5f,bridge=pubbr",
"mac=00:16:3e:5b:44:60,bridge=virtbr"  ]

Interfaces are associated with both bridges properly, but only an eth0
device appears in the domU.

If the low-order bits are magic in a MAC, then maybe my second one is an
invalid, but I don't find any documentation of such; the low two bits of
the *first* byte have meanings, but I haven't touched them.
