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?
