Trying to upgrade guest VM

I have a VM guest running Sles 10 Sp3 on Sles 11 sp1 host. I have added a cdrom mapping in the cofig for the guest to the Sles sp1 iso image. However when I boot the guest it will not boot from the iso. I exported out the config information and changed the bootable flag from 0 to 1. I then imported the config back in. When I go to boot the VM I receive the following error, "xend.err “bootloader did not return any data”. If I remove the iso mapping the VM boots fine. However I need to boot from the iso in order to upgrade the OS. Any ideas?

Hi
Did you check the iso image md5sum?

Have you also read this document; https://www.suse.com/support/kb/doc.php?id=7010200
“There is no supported direct migration path to SLES/SLED 11 SP2. An update has to be performed from SLES/SLED 10 GA to SP 1, then to SP 2, further to SP 3, and then to SP4 by using the respective boot media.”

Here’s how I have done vm upgrades:
Shutdown old vm.

On virt-manager create new vm (like vm-upgrade) with option "yes I need
to install operating system’. For disk config point to existing disk
image/partition. For installation media point to iso/cdrom.

After installation/upgrade shutdown vm-upgade and start old vm.

If having any issues compare vm vm-upgrade config files.

Take backups before you start if you want to be sure.
