Yeah, I was just prep'ing a reply to tell you not to get too excited.
A working bridge configuration for you should look like:
$ brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no vif0.0
peth0
vif3.0
At the moment it appears that the xen network-bridge script was
very unsuccessful in putting your eth0 interface onto the bridge.
Can you check the xen logfiles as well of the syslog to see if there is
any indication of why this failed.
My initial gut feeling was that it was because you were using aliases
(ie you have an interface called eth0:0). I recommend that you take down
that eth0:0 interface and try again.
However, I must note that I did a quick experiment here involving
aliases and the xen scripts still worked (though eth0:0 was
changed to eth0:2). Utlimately you will be better off using
"ip addr add" to add additional ip addresses to your interfaces
rather than using old-style aliases - but this probably won't solve
all your problems here unfortunatly.
Let us know how you get on searching the logs, and trying again without
eth0:0.
Also, if you are running iptables this is going to get in the way of any
tests you conduct - so watch out for this.
