I`m trying to use this how to but im stuck on the following error

11-1-2012 13:10:23 Error: Starting VM ‘snorby02′ – Internal error: XenguestHelper.Xc_dom_linux_build_failure(2, ” elf_xen_note_check: ERROR: Will only load images built \\\”")

This is my menu entry

menuentry ‘Ubuntu, with Linux 2.6.32-37-generic’ –class ubuntu –class gnu-linux –class gnu –class os {
recordfail
insmod ext2
set root=’(hd0,1)’
search –no-floppy –fs-uuid –set 240ff737-43ec-4276-8c5e-8d254939acdb
linux /boot/vmlinuz-2.6.32-37-generic root=UUID=240ff737-43ec-4276-8c5e-8d254939acdb ro
initrd /boot/initrd.img-2.6.32-37-generic

and i am pasting the following lines when running the script

/boot/vmlinuz-2.6.32-37-generic
root=UUID=240ff737-43ec-4276-8c5e-8d254939acdb ro
/boot/initrd.img-2.6.32-37-generic

Why is this going wrong do i have to past more or less information (can u add an example step after the run makepv.sh my-vm-name )

Update on my previous post: I managed to fix the problem with the -server version of the kernel. In the -server version of the kernel, xen_blkfront is compiled as a module, but is required to mount the root file system. So if the initrd system is loaded by grub, it does not know how to mount /dev/xvda1, because xen_blkfront is not loaded. I added xen-blkfront to /etc/initramfs-tools/modules. I also created a hard-link from /lib/modules/2.6.32-36-server/kernel/drivers/block/
/xen-blkfront.ko to /lib/modules/2.6.32-36-server/initrd/. Afterwards, i recreated the initrd image with update-initramfs (use the correct options to create the initrd image also for the kernel that is not currently running). I don’t which of the two (adding to modules, or lining to the initrd directory) did the trick, so maybe only one of the two is required.

This makes that the -server version boots perfectly, but migration still fails. Anybody any idea how to fix that?

I had the same migration problem with kernel 2.6.32-36-generic. I therefore tried to install the -server kernel, resulting in a boot configuration that could not find my boot and root disks anymore. I can go back to the -generic kernel. Does anybody know the specific difference between the -generic and -server kernels that could cause the difference in behaviour when life migrating?

This works great, thank you. I have a question.
What would be the best way to clone an Ubuntu system, that you have performed this operation on?
I made a copy of a VM after doing this, but now I’m worried that the same disk UUID will become a problem. Is there a way to change this, or should I be concerned?

Did not work when I tried it and now I have to convert it back to HVM. Might have to hack the script to go back and forth. Should be able to detect if the specified machine is in HVM or PV and ask user if he wants to conver it to the other, right?

GREAT TUTORIAL! Thanks for the script, too! Worked as a charm on XenServer 5.6SP2 and Ubuntu 10.4 Server x64.
