I did not manage to get a stable bridge networking with bonding and SLES10 that
way. Maybe tell us which bonding mode you are using at least.


I've tested it using mode 1 and mode 5. The NIC's are HP NetXtreme II
BCM5708S Gigabit ethernet's if it's relevant.

I did have some issues inside the domU's now you mention it, I had to
"fix" the gateway's arp table entry with a tiny bootup script, since
it appears receive a corrupted arp entry. After that fix: everything
works stable, failover works and speed is as good as it gets.

Thinking about that fix, it could be arp in dom0 gets corrupt as well,
so I tested adding fixed arp entries in my heartbeat dom0's... but
still, heartbeat goes down if I bring up the xen networking. Other IP
traffic works just fine.
