Re: [Xen-users] centos 5.6 upgrade to 4.1 - no DomUs listed

[Randy Katz <rkatz@xxxxxxxxxxxxxxxxxxxxx>]

try booting with pci=nomsi on the kernel line,
If you setup networking according to this then things should be working, 
and no need to
use vif in the bridge line:

One of my working confs looks like this (CentOS 5.6 Xen 4.1):

name = "test1"
memory = "512"
disk = [ "phy:/dev/vg1/test1,xvda,w" ]
vif = [ 'mac=00:16:3e:aa:aa:91,bridge=xenbr0' ]
vcpus=1
on_reboot = 'restart'
on_crash = 'restart'
bootloader = "/usr/bin/pygrub"

on node:
# netstat -rn
