[Xen-users] DomU stops booting

[Martin Lang <mlg-hessigheim@xxxxxx>]

Hi,

I installed Xen3.3 on a Debian (etch) system. My DomU is also a Debian
(etch) system on a logical volume. I populated the volume by mounting it
from the Dom0 and used debootstrap. The config file for the DomU is:

kernel = "/boot/vmlinuz-2.6.18.8-xen"
ramdisk = "/boot/initrd.img-2.6.18.8-xen"
memory = 32
root = "/dev/xvda1 ro"
disk = ['phy:xenix-lvm/obelix_root,xvda1,w',
       'phy:xenix-lvm/obelix_swap,xvda2,w']
vif = [ '' ]

The kernel for the DomU is the kernel I get from the Xen3.3 build
process. Starting the DomU seems to work, at least I get no error from
xm create. When I want to switch the console to the DomU with XM console
the DomU seems to hang during boot. I get the following and then the
output stops. Nothing happens anymore. No login prompt. The only thing I
can do is to shutdown the DomU again.

Can someone please help?

Thanx

  Martin
