VFS: Unable to mount root fs on unknown-block(1,0)

["Eric S. Johansson" <esj@harvee.org>]

google yields nothing except for indicating that it is a boot loader 
problem.

my dom0 partition is on a 9 GB SCSI disk drive.  I have a raid1 device 
(md0) which I have created a series of partitions via lvm2. on boot,

xm create /etc/xen/xm-single -c

I get what looks like a normal boot until

TCP: Hash tables configured (established 4096 bind 8192)
NET: Registered protocol family 1
NET: Registered protocol family 17
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(1,0)
  <0>Rebooting in 1 seconds..

the configuration file defines the disk as:

disk = [ 'phy:bigraid/root_harvee,sda1,w' ]

I've tried root definitions

root = "/dev/sda1 ro"

and no root definitions.

a pointer to the documentation I should be reading would be helpful.
