[kernel-xen] error 13: invalid or unsupported executable format

Probably - depending if you can disable EFI in the BIOS and use legacy
booting. You'll have to reinstall the OS after changing this setting
(not an upgrade).

I'm not sure if anyone here uses an EFI based boot system that can test
- but it would be nice to know... I don't have any EFI based hardware
that I can test with...
