Well, I used a DRBD block device, so the -oloop mount option won't
work to mount my image. Oddly, I can't seem to mount the block device
either. Perhaps that's my real problem? (Though why it worked the
first time....?)
Anyway, my xen config file looks like this:
# Automatically generated xen config file
name = "mail"
memory = "512"
disk = [ 'phy:/dev/drbd2,xvda,w', 'phy:/dev/VolGroup00/
mailSwap,xvdb,w' ]
vif = [ 'mac=00:16:3e:75:d2:20' ]
bootloader="/usr/bin/pygrub"
on_reboot = 'restart'
on_crash = 'restart'
... where /dev/drbd2 is the DRBD block device holding both /boot/
and /. If I use fdisk to get a listing on /dev/drbd2, I see:
Disk /dev/drbd2: 31.4 GB, 31474057216 bytes
255 heads, 63 sectors/track, 3826 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/drbd2p1 * 1 13 104391 83 Linux
/dev/drbd2p2 14 3826 30627922+ 8e Linux LVM
So it *seems* like I should be able to mount /dev/drbd2p1 or /dev/
drbd2p2. Alas:
# mount /dev/drbd2p1 /mnt
mount: special device /dev/drbd2p1 does not exist
# mount /dev/drbd2p2 /mnt
mount: special device /dev/drbd2p2 does not exist
I'd be happy to blame this on DRBD, but this did work for both
install and after the first reboot....

So at present you couldn't create XenU with that image again? I
think maybe your XenU image is broken.
Maybe you can do a manually mount that image file and check if /etc/
fstab is there.
mount -oloop xenU_image_file /mnt
