My primary concern is for the moment to fix dom0 networking before
thinking of domU's :-)
I've ran tcpdumps in a healthy environment (just eth0 + heartbeat +
xenbr0) and in the bonded one... contents of the HA packets are
exactly the same; NS_ackmgs and status ones.

I looked into the arp issues, but realised I couldn't have any,
because heartbeat is multicasting, and arp multicast flags seem to be
set. I enabled multicast in the function create_bridge from
xen-network-common.sh so the bridge should support multicast. Perhaps
it's something with the software bridge not forwarding the multicasts
properly in xenbr0.

I just tried the network-bridge script from xen 3.03 under sles 10,
but that one doesn't even bring up the network at all.
