[Xen-users] domU unbootable after unknown error

[Charlie Farinella <cfarinella@xxxxxxxxxxxxxxxxxxxxxxxx>]

I've done something apparently, but can't for the life of me figure out 
what.  Perhaps someone can help:

I have an LVM based domU which has been working without problem for 
weeks.  I made some final changes to it last week, shut it down and ran 
the following to create a backup image:

dd if=/dev/VolGroup00/wspd of=mail2.img bs=1M

At least this is the only thing I can remember doing.
Since then when I try to start it, I get the following:

[root@xen3 xen]# xm create wspd -n
Using config file "./wspd".
Traceback (most recent call last):
  File "/usr/bin/pygrub", line 651, in ?
  fs = fsimage.open(file, get_fs_offset(file))
  IOError: [Errno 95] Operation not supported
  No handlers could be found for logger "xend"
  Error: Boot loader didn't return any data!
  Usage: xm create <ConfigFile> [options] [vars]
  Create a domain based on <ConfigFile>.

My config file looks like this:

name = "wspd"
uuid = "e0dfbc97-4049-c17f-1a86-957dff290125"
maxmem = 384
memory = 384
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ "type=vnc,vncunused=1,keymap=en-us" ]
disk = [ "phy:/dev/VolGroup00/wspd,xvda,w" ]
vif = [ "mac=00:16:3e:29:99:cf,bridge=xenbr0" ]

Hints of any kind are appreciated.
