[Fedora-xen] "Invalid kernel" error on PV creation -- what's invalid?

I don't know if this is a Fedora, Xen, Cobbler/Koan or local config problem.
Or some combination.
I'm using cobbler+koan to create a PV VM.
hostOS = Fedora 8, guestOS = Fedora 8.
On attempt to create the PV, it chokes at (console error)
"Error: (2, 'Invalid kernel', 'xc_dom_find_loader: no loader found\n')"
I see the same in /var/log/xen/xend.log (detailed tail, below), so I suspect
it's a problem with xen.
The vmlinuz & initrd.img I'm using, by reference in 'cobbler distro ...'
invocation are pulled from
http://mirrors.kernel.org/fedora/releases/8/Fedora/x86_64/os/images/xen/, so
I'm not clear what's "Invalid" about the kernel.
Any suggestions?
Jimmy
