RE: [Xen-users] Xen 3.0.4 on RH EL 4.4 - can't make it boot kerne l

["Foreman, Tim" <tforeman@xxxxxxxxx>]

I didn't want to make the Xen kernel the default until I was
sure that it would boot correctly.

When I put the root=LABEL=/ on it I get an error:

mkrootdev: label / not found

Hi Tim,

The first thing I noticed in your grub.conf is that your xen configuration
have index value 0f 2, while the default=0. It should be default=2. I hope
this should sort the obvious problem.

Secondly, why are you not using root=LABEL=/ rather root=/dev/hda1! 

Cheers
Omer

I'm trying to build a Xen server on Enterprise 4.4 and I can't
get the Xen kernel to boot.

I installed the kernel rpm and the Xen rpm and my grub.conf looks
like this:

        module /boot/initrd-2.6.16.33-xen_3.0.4.1.img

When I try and boot the Xen kernel it stops with the following errors:

Loading ide-disk.ko module
ide_disk: no version for "struct_module" found: kernel tainted.
Creating root device
Mounting root filesystem
mount: error 6 mounting ext2
mount: error 2 mounting none 
Switching to new root
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing: Attempted to kill init!

I did some googling and found some indications that it might have been 
related to using the ext3 filesystem, so I rebuild the server with ext2
and got the same results.

Any suggestions?
