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

I have sucessfully installed xen domain 0 on a Debian system and have
created a virtual disk in it's filesystem and used debbootstrap to
install debain on it. In the config file for the virtual machine I
have:

kernel = "/boot/vmlinuz-2.6.11.9-xenU"
disk = [ 'file:/usr/local/xen/images/debian_01,sda1,w', 'file:/usr/local/xen/images/debian_01-swap,sda2,w' ]
root = "/dev/sda1 ro"

the filesystem for /usr/local/xen/images/debian_01 is xfs and I have
already been able to mount it. xfs support is in the xen kernel.

when running xm create -c debian_01-1 vmid=1 it fails with the
following:

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

Sorry for not getting to this sooner. Have you found a solution yet?

Do you have DevFS support in the domU kernel? If so, that won't work - you
need static /dev nodes (or udev) in a domU.

Cheers,
Mark
