Additionally, the menu.lst for grub is as follows:

title Debian GNU/Linux, Xen 2.6.11xen0, testing 2005.06.18
kernel=/xen.gz dom0_mem=32768 noreboot
root (hd0,0)
module=(hd0,0)/xen-linux-2.6.11charliexen0 root=/dev/sda2 ro console=tty0 
console=ttyS0 showopts selinux=0
### BEGIN AUTOMAGIC KERNELS LIST

-M

Alright, thank you for the "noreboot" kernel option!

Here is the full err:

Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "sda2" or unknown-block(2,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

Doing a bit of research on the error message, found the following threads on
xen-devel:
http://lists.xensource.com/archives/html/xen-devel/2004-10/msg00382.html
http://lists.xensource.com/archives/html/xen-devel/2004-12/msg00470.html

I'm thinking this might not be a xen problem, but a grub problem?

Still working on the issue, any tips would be appreciated.

Thanks.
