Yes, when you add that <ip family='ipv6'> line and then
restart the network (virsh net-destroy TheCommons && virsh net-create TheCommons)
it should have started radvd automatically. The guest should then have automatically
got an address from radvd. This all works fine in my testing.

That other bug is irrelevant, refering to much older libvirt prior to the
introduction of IPv6 support.
