It’s always eth0 that shows a different aggregator ID. Changing the cables

switch is correctly configured for the port channel.

The only difference between the 2 servers is one is running Xen
(kernel-xen-2.6.18-194.32.1.el5.centos.plus) so I have the usual virtual
interfaces and bridges.

Any ideas what might be happening?

Is something that needs to be “fixed” or is it not really a problem?
eth0      Link encap:Ethernet  HWaddr 1C:C1:DE:74:97:5C
peth0     Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
The presence of "peth0" shows you still use the default xend's
network-bridge script. Comment it out from /etc/xen/xend-config.sxp,
and create bridges manually on top of your bonding using OS config
files (/etc/sysconfig/network-scripts/ifcfg-br*). There's a recent
example on this list (with vlans on top of bonding) from Donny Brooks,
search the archive if you need it.

If you need help setting this up I may can help. I have it running properly on a few centos 5.5 machines with xen4 currently. I know how frustrating it can be too.
