I've got a system with 3 nics. eth0 is down, eth1 is external and eth2 is
internal. (This is in a "lab" so the "external" is a 10.x.x.x address.)
Before starting xen, the broadcast for eth2 is 192.168.1.255, after starting it
becomes 0.0.0.0 - which sure doesn't look right to me - plus I'm getting
networking problems. Been digging for a while and not having any luck.
This is a xen 3.0.1 system, logs and config files below.
Any ideas on this one?
My ifconfig before starting xen:
