[Fedora-xen] fedora core 7 and Xen

[Edward Pasek]

After numerous attempts to get anything running as a guest OS I continue
to run into errors. I have tried each install method atleast 4 times
from the quickstart guide. So far my results under fedora 7 and Xen have
failed. So far if I try to install core 6 or fedora 7 i386 I get kernel
panics and this dump

if I install the x86_64 it just hangs and I get this in xm dmesg
(XEN) *** Serial input -> DOM0 (type \047CTRL-a\047 three times to
switch input to Xen).
(XEN) grant_table.c:265:d0 Bad flags (0) or dom (0). (expected dom 0)

I've disabled selinux, tried building my image in /var/lib/xen/images/
and several other places. I've removed and reinstalled xen virt-maanger
kernel-xen, I've tried an upgrade from 6-7, changed settings in my
config for cpus, mem, ethernet bridging. 

I'm running Xen on a dell 2900 with 4 Xeons (x86_64) with the vt flags,
8 gb ram and a 1000 gigs of disk space.
