Next, when I look in my menu.lst file I see there is no xen kernel configured.

ls /boot shows that vmlinuz-2.6.22-12-xen does in fact exist.

If I manually edit my menu.lst and try to boot with the xen kernel, grub reports Error 13: Invalid or unsupported executable format.

This was being caused by linux-image-xen not really being usable without the hypervisor installed. Perhaps a dependency should be set here. Once the ubuntu-xen-server package exists for amd64, that will also help alleviate the issue.

This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue. Thanks.

I think I ran into this myself.

Xen Server 5.5
Installing Ubuntu 8.04 TLS into XEN using these instructions:

In the section regarding "You now need to workaround a bug in grub. Due to the switch in recent versions of Linux to work with the hypervisor-independent paravirt_ops interface, update-grub doesn't update the grub configuration with your newly installed Xen kernel. :"

I've done the "sudo apt-get install linux-image-xen"

and it installed vmlinuz-2.6.24-24-xen but didn't put it in the grub list.

When I manually modify menu.lst to use the xen kernel for booting it gives the Error 13.

Ask if you need further info for troubleshooting.

Not sure if this issue is specific to amd64 build or not, haven't tried the x86 ubuntu
