Aha! That fixed it. Turns out that debian bridge-utils sets the
default to 15 for bridges.
Manually setting it to 0 with 'brctl setfd br0 0' or setting the
'bridge_fd' parameter to 0 in /etc/network/interfaces solves the issue.
I think libvirt is doing something about this, copying list for further
info.
