I wanted to clarify on this point. Understood as far as the above, but the issue is that the PHYSICAL MAC was changed to FE:FF:FF:FF:FF:FF.
This went so far as to still have this value even after rebooting on the standard kernel and then uninstalling XEN:
# dmesg | grep eth1 eth1: RTL8110s at 0xee156c00, fe:ff:ff:ff:ff:ff, XID 04000000 IRQ 22
What ever happened during the first boot of XEN caused a permanent change to this NIC as far as I can tell.
Maybe because you are looking at the bridge's mac and not the ethernet's which would be peth0.
Actually that would be peth1
For a Xen server I find it better to disable the Xen network scripts and setup a static bridged or routed setup.
Then it is predictable and iptables is infinitely easier to setup.
