Hello All.
I have been attempting to get a Xen guest to boot on a Dell 2650 running FC5.
The machine has a 205GB hardware RAID disk controlled by a Dell PERC 3/Di rev 1. The
machine is fully updated via yum to all the stock repos. It's running the Xen package
from Fedora.org
Here is the fstab file for the host domain (Domain-0):
------------------------------------------------------------------------
/dev/sda2 / ext3 defaults 1 1
/dev/sda1 /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/sda3 swap swap defaults 0 0
------------------------------------------------------------------------
Here is the output of fdisk -l
------------------------------------------------------------------------

I have attempted to use LVM-backed VBDs as instructed here:
http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03330000000...
Here is my config file for the LVM-backed VBD named, psdev0

def vmid_check(var, val):
val = int(val)
if val <= 0:
raise ValueError
return val
xm_vars.var('vmid',

xm_vars.check()

"xm info" has this to say about the running Domain-0:

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)
No matter what I set the root= option to be, the result is the same.
Oh, one last config file: my grub.conf from Domain-0
