Chris,

Thanks for the pointer to check that log file, it actually says:

---------------------------------------------------------
Nothing to flush.
ERROR: Kernel not a Xen-compatible Elf image.
ERROR: Error constructing guest OS
---------------------------------------------------------

Do I perhaps need to point it somehow at the Xen kernel and initrd here:

http://zeniiia.linux.org.uk/pub/distributions/fedora/linux/core/5/i386/os/images/xen/

instead of

http://zeniiia.linux.org.uk/pub/distributions/fedora/linux/core/5/i386/os/
