This is fresh install of CentOS v6 and Xen v4.1 on a new Dell server following 
the tutorial posted at: http://wiki.xensource.com/xenwiki/RHEL6Xen4Tutorial
 
Every thing went just fine, yet virbr0 won't work and when I run brctl show I 
get the following error message:
 
[root@pe1950 ~]# brctl show
bridge name     bridge id               STP enabled     interfaces
virbr0          /sys/class/net/virbr0/bridge: No such file or directory

8000.000000000000       yes
 
FYI, /sys/class/net/virbr0/bridge does exist. That said I can't install any 
DomU because virbr0 is down/not working.
 
I read all threads about this problem, but none gave any solutions. Please 
help. Thank you
