Xen users - Oct 2005 - Fedora install: Domain0 allocation is too small for current kernel

Hello,

I''ve just installed Fedora Core 4 and I''m now trying to
install xen. I''m
follwing the redhat quickstart but when I try to boot the xen kernel I get
the sam errors as described in a previous message to this list. Nobody has
answered, so I thought it was a good idea to repost it...

Greetings,

I installed Fedora a few weeks ago and have been using the basic
instructions from http://www.fedoraproject.org/wiki/FedoraXenQuickstart.
This worked well, however since then there was a new linux kernel 2.6.13 and
the base development Fedora kernel was updated. Xen was also updated, and
it''s been updated once more since the new kernel also. Niether of the
new
Xen kernels boot.

This one doesn''t boot:
-----------------------------------------------
title Fedora Core (2.6.13-1.1530_FC5xen0)
root (hd0,0)
kernel /xen.gz
module /vmlinuz-2.6.13-1.1530_FC5xen0 ro root=/dev/VolGroup00/LogVol00
module /initrd-2.6.13-1.1530_FC5xen0.img
-----------------------------------------------

Nor does this:
-----------------------------------------------
title Fedora Core (2.6.13-1.1529_FC5xen0)
root (hd0,0)
kernel /xen.gz
module /vmlinuz-2.6.13-1.1529_FC5xen0 ro root=/dev/VolGroup00/LogVol00
module /initrd-2.6.13-1.1529_FC5xen0.img
-----------------------------------------------

The error is:
-----------------------------------------------
Panic on CPU 0:
Domain 0 allocation is too small for kernel image
-----------------------------------------------

I''ve tried adding extra argument on boot:
-----------------------------------------------
title Fedora Core (2.6.13-1.1526_FC5xen0)
root (hd0,0)
kernel /xen.gz dom0_mem=131072
module /vmlinuz-2.6.13-1.1526_FC5xen0 ro root=/dev/VolGroup00/LogVol00
module /initrd-2.6.13-1.1526_FC5xen0.img
-----------------------------------------------

I also tried ''dom0_mem=262144'' and
''dom0_mem=65536''. I know the
/etc/grub.conf changes are working because ''noreboot'' is
working.

Ideas?

The system is a HP DL380 Xeon 3.4 GHz with single CPU (with hyperthreading)
and 1 GB of ram.

Regards,
Dave Seddon

"2.6.12-1.1456_FC4xen0 fails to boot (2nd Case)"
<https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169157>

The work-around for me, at least with that kernel version, is to use the
xen package from <http://people.redhat.com/riel/xen_for_fc4/>. However
I''ve long since lost faith in having a stable xen server based on the
FC4 packages (and arguably the xen3 branch)
