Thanks for your reply. I was so occupied with troubleshooting that I forgot
to mention the OS & Xen version :)
My CentOS version is
CentOS release 5.7 (Final)
Linux 2.6.18-274.7.1.el5xen #1 SMP Thu Oct 20 17:06:34 EDT 2011 x86_64
x86_64 x86_64 GNU/Linux
and Xen v3.0.
I tried creating bridges the same way you did and succedded. I also tried
doing the same via ifcfg scripts, and it also worked.
I have no problem with creating bridges and connecting them with physical
ifaces, but I can't start my VM's (most of the time one VM start but the
other one hangs while trying to initalize eth2 that is connected to my
second (non default - xenbr1) bridge)).
The only diference between your config and mine is that I have vifname-s
listed (example below):
vif = [
"mac=00:16:3e:57:de:0d,bridge=xenbr1,script=vif-bridge, vifname=vif4.1" ]
I'm not saying that this could be the problem, but since I'm slowly running
out of ideas - it's a longshot :)
So, to sum it all up - I can create bridges properly, but my VM's hang when
they try to bring up vifaces connected to the xenbr1. Also, I have no
problem with having only one bridge active - problem appears when I have
