That would be nice, but I think that a semantics where libvirt is in
charge of telling which qemu process is to listen on which of the
network IP addresses is as reasonable (and may potentially better, as
libvirt has more knowledge of the host)

Anyway, if the virtual network is bridge-based, I could live with
passing the single IP of the bridge for qemus that do not support this
feature.
