[Xen-users] Xen bridge acting weird

[Matthew Palmer <mpalmer@xxxxxxxxxxx>]

I've got some problems with a Xen system and it's network bridges.
Initially, when the system starts up, the networking all appears to work OK. 
However, when I restart networking or Xen, the bridge basically packs it in
almost entirely -- other machines on the physical network cannot communicate
with the domU hosts.  Nothing short of a reboot will restore things back to
their proper state (including completely shutting down all domains,
restoring bridging back to it's native state, stopping Xen, and then
bringing everything back up).

I'd put it down to complete catatonia, except for two things:

* Connections from the dom0 to the domUs still work OK;

* ARP responses and requests get through OK -- it's only every subsequent
packet which cops it in the neck.

Has anyone seen this sort of behaviour before in a bridge, and was there any
useful solution found?

Environment: Ubuntu hoary dom0 and domU, running 2.6.11 kernels, Xen 2.0.6 
built from the Debian source packages.
