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....

Subject: [Fedora-xen] Unable to reboot a domU
I installed a domU on x86_64 today, and was very happy. I even logged
into it and saw that things seemed to be working, and all was well. I
tried to reboot it, and now the domU kernel panics every time I try
to boot. :(
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
The bug is 185603, and the console end with:
no fstab.sys, mounting internal defaults
Switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
Kernel panic - not syncing: Attempted to kill init!
