Re: [Xen-users] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3, 1)

[Yvette Chanco <yentlsoup@xxxxxxxxx>]

Julien,

Looking at your menu list, I'm curious about this line:

module          /initrd.img-2.6.11-ocxen0

Did you create an initrd.img by hand? That kernel is minimal, and was
designed to boot without need for an initrd (as long as the hardware
which contains your root device is supported, which it appears to be).
You might want to try removing that line. If that doesn't help, please
post a dmesg from a boot for a non-xen kernel

-Yvette
