[Xen-devel] Newbie problem: disk error launching FC3 in non-0 domain

[Roland Paterson-Jones <roland@xxxxxxxxxxxx>]

Hi again

I have a minimal Fedora Core 3 image running fine as domain 0 (thanks 
and sorry for the previous FAQ query) using both the standard install 
ramdisk image, and the FC3 ramdisk image downloaded from xen sourceforge.
However, I can't get it running in a non-zero domain.

In brief, I have a full FC3 installed on /dev/hda1, which I typically 
use as my domain 0 OS. Then I have a minimal FC3 installed on /dev/hdb2.
I can boot into the minimal FC3 on /dev/hdb2 as domain 0 under Xen 
without a problem.
I'm trying to 'xm create' the minimal FC3 from the full FC3 under Xen, 
but I get a disk error. Here's the relevant log:

Any idea what the problem is?

Thanks again
