Re: [Xen-users] Unable to access network after installing Xen 3.1

["John T. Yocum" <john@xxxxxxxxxxxxxxxx>]

Hi Arik,

What do the configs for the domU's look like? I've got a system running 
CentOS 5, with the included version of Xen, and haven't had any problems 
with network access.
Here's an example config from one of my working domU's.

kernel = "/boot/vmlinuz-2.6.18-8.1.3.el5xen"
ramdisk = "/boot/initrd-2.6.18-8.1.3.el5xenU.img"
memory = "1024"
vcpus = "8"
name = "cp"
vif = ['bridge=xenbr0,mac=00:16:3e:01:01:01']
disk = ['phy:hn1/cpRoot,sda1,w',
        'phy:hn1/cpHsphere,sda2,w',
        'phy:hn1/cpSwap,sda3,w']
root = "/dev/sda1 ro"

--John
