It would be very useful if someone would write and post
a complete "recipe" for the steps to get RHEL4 running as
domain0 on Xen/ia64, including such things as:
- where to download the source of elilo
- how to apply the elilo patch and generate a new elilo
- what to specify in the elilo.conf file to boot RHEL4
I would be happy to beta-test the recipe as I would like
to update my Xen test system to RHEL4.
