[Xen-users] Xen dom0 doesn't find root device - kernel panic

["Rene Bartsch" <ML@xxxxxxxxxxxxx>]

Hi,

I've installed xen-2.0.5 from source on gentoo, but the xen dom0 kernel
doesn't find the root device:

############################# snip ######################################

Kernel panic: VFS: Unable to mount root fs on unknown-block (3,3)

############################# snap ######################################


grub.conf:

How to I tell Xen the correct root device?

Thanx for any hint
