[Fedora-xen] FC6+xen guest boot issue

Hi All,

I'm trying to set up Xen using FC6 as dom0, and am having zero success
getting any guest OS to run.

I've read the quickstart guide, but it's of little use because it makes
two very large assumptions:

1. I want to install FC6 as a guest.
2. The hardware has internet access.

I want to have RH7.3 running as a guest (but I'll settle for *anything*
right now), and the machine I want to install on is behind a firewall,
and has no internet access at all.

I've tried the Documentation at xensource.com, and even tried
downloading images from jailtime.org - no matter what I do, I encounter
the following error:

VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)

(I've tried both hda1 and sda1 as root, neither one works.)

The xen config I'm using is as follows:

kernel = "/boot/vmlinuz-2.6.18-1.2798.fc6xen"
memory = 256
name = "test"
vif = [ '' ]
disk = ['file:/xen/test.img,sda1,w','file:/xen/test.swap,sda2,w']
root = "/dev/sda1 ro"

The file /xen/test.img exists, is not mounted by dom0, and contains a
linux system (verified via mount -o loop, and umounted before I try to
run xm create.)
According to the Xen documentation, I believe this should work.

Is there a fc6-specific initrd that I need?  Is there any documentation
that might provide some insight on installing non-FC6 guests onto a FC6
dom0?

Thanks,
Karl
