Hi,

Your kernel config has support for Reiserfs? If it haven`t reiserfs support the system does not go to start. If the support it is compiled as module  you need the ramdisk = '/initdr.img....' line. If the support it isn`t compiled as module, the system must start.

2006/7/19, FreiNet Technik <xen-users@xxxxxxxxxx>:
Hello,

i upgraded a xenserver from version 2.0.7 to 3.0.2 and the OS from
Debian Sarge to Debian Etch.
I now use the 2.6.16-xen Kernel (for Dom0 and DomUs) with all required
modules in an initramfs.

The Dom0-Partitions run on LVM (all but /boot) and use ReiserFS.

When I try to create DomUs with my old filebased images from 2.0.7, only
those with ext3 work (e.g. fedora). Debian images with reiserfs  break
on boot with

("Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(8,1)").

It seems to me that ReiserFS is unknown in DomU.

I verified this by creating a testimage with debootstrap, first on a
ReiserFS formated file (which didn't boot) and then the same on a Ext3
formated file (which did).

Has someone experienced the same problems? And even better, solved them?
Has this maybe something to do with udev and initramfs?

Thanks for help,

Holger
