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

["Eric S. Johansson" <esj@xxxxxxxxxx>]

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.

The basis of Abelard's philosophy, which he taught to Heloise, was
that logic had to be applied to religion in order to arrive at the
truth.
