I have a server with dual etherports, eth0 and eth1. Before starting xend, I can connect to the server (dom0) on both IP's. I have Xen configured so that it sets up the network-bridge on eth1; ie, in /etc/xen/xend-config.sxp:

(network-script 'network-bridge netdev=eth1')

When I start xend, the bridge starts up on eth1, and then I can't connect to that interface externally, which is expected. The domU's start up and setup their vif's, and they can connect to the network fine too. Also, I can connect to dom0 on eth0, which is not xend's netdev.

The weird thing is that the network connection on eth0, after xend starts, is intermittent. It seems to go down about once an hour, for a period ranging from 10 minutes to 70.

Anybody have any insight?

TIA
Rich
