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.

Dave Seddon
