[CentOS-virt] Fedora 12 2.6.31.5-127.fc12 domU on CentOS 5.4 2.6.18-164.6.1.el5xen fails to boot

Scot P. Floess <sfloess at nc.rr.com>

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".
