Unfortunately, kernel-xen in F-9 does not support Dom0, so this is expected.

If you require a Xen Dom0, you'll need to use F-8 until F-10.

See here for more details:

F9 paravirtualized host can't be installed on F8 too. Is it a known problem?
This kernel works on none system.

Comment 3 Mark McLoughlin 2008-05-19 12:17:56 UTC

Jan: you need to update your F-8 Dom0 to kernel-xen-2.6-2.6.21.7-2.fc8

See bug #436859 and:

Comment 4 Jan ONDREJ 2008-05-19 13:07:39 UTC

Thank you. Just for anyone reading this the -3.fc8 kernel is required.
Works for me.
