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.
