I just installed F11... When attempting an "xm create -c" I get the
following failure... I do use Cobbler and KOAN and have my setup set to
use Xen pv... Do I need to specify something special for the guest
kernel? I know for CentOS 5.4 guests - I really don't do anything special
with xm create...
Using config file "/etc/xen/fedora-11-vm-i386".

So, I am going to show my ignorance here... Is there anything special I need
to do to use those kernels? I could have sworn when I tried either F 10 or F
11 - I couldn't work it without qemu running. But I could be wrong :)
Maybe I should retry 11...

I have a silly question... I did some goggle'ing around and it appeared
to me that Fedora 12 should work as a Xen guest (domU). Is this true? I
know 10 and 11 I'd have to use KVM....
Fedora 10, Fedora 11, and Fedora 12 all work as Xen PV domU, with the
included (pvops) kernels. Earlier Fedora versions work too.
Fedora 12 also works as Xen dom0, if you install the external unofficial
xendom0 kernel rpm.

I've only got the one virtual disk. /boot is on xvda1 with / and swap
in LVs. The PV is xvda2.
Double check the F12 /boot type. It needs to be ext3 for now.
RHEL5 / CentOS5 doesn't have ext4 pygrub support yet.
Xen packages on F12 host/dom0 do support ext4 pygrub though.

If /boot is on another virtual drive, make sure it's the first one in
the VM's 'disk' listing (/etc/xen/foo). I remember reading that Xen
gives only the first disk to pygrub as an arg.
/usr/bin/pygrub is a Python script. Probably printing the 'file'
var to
stderr before the line fsimage.open(file, get_fs_offset(file)) shows
what it's trying to open.

I specifically call out to create an ext3 filesystem in the
kickstart file for /boot. I did neglect to mention that in my
original post.

This looks like your host doesn't support the filesystem your domU's
using. I think Fedora's on ext4 by default. One solution is to use
ext2/ext3 for the domU's boot media or partition.
