Greetings,

Sometimes - at random it seems - ethernet interfaces start swapped
(i.e. eth0 in domU is connected to xenbr1 instead of being connected
to xenbr0 . Below is the relevant portion of xend.log when such swap
takes place.
I'm using Xen 3.0.4_1 on 32bit Linux.

Any ideas ?

RedHat uses a little setting in /etc/sysconfig/network-scriptss/ifcfg-eth* called "HWADDR" to associate a MAC address with a specific interface. It's especially useful when sometimes having a wireless device turned on and turning up as eth0, or not and winding up with a wired port as eth0.
