Might be worth a try. When it drops off, what do you have to do to get
it back on? Does rmmod/insmod'ing the module work?

Perhaps just try a different 100Mb/s card.

Edit xend-config.sxp to use (network-script network-router) and
(vif-script vif-router).

There certainly shouldn't be an issue with 100Mb/s. Whenever we've seen
this before its been because the Ethernet card has been bad and looses
carrier.

Please can you try moving over to the routed rather than bridged scripts
and see if it still occurs. I think we're going to make routing the
default in 3.0 anyhow.

On one of set the machines that I have deployed I'm having problems DOM0
falling of the network when copying large files over NFS. On the other
set of machines, I've never seen this problem. The immediate difference
that comes to mind is that one of the interfaces on the first group is
100Mbit. Does 100Mbit have such severe performance issues that it could
cause the bridge to just stop forwarding packets?
