First, a question. Have you ever tried to install RH 6.2 on a modern
Intel CPU?
My guess is it wouldn't work. CPU-wise, Xen will pretty much present
whatever CPU present at dom0 to domU. Meaning if it crashed on a real
machine, it would also crash on a HVM guest.

That being said, I believe the earliest RHEL version certified to run as
HVM guest is RHEL3, and the earliest RHEL version certified to run as PV
guest is 4.5.


Good to know - i've just spend a few days trying (and eventually succeeding) to install RHEL 4.4 x64 as a PV guest on an Intel Xeon 3050.

Do you have a sample .cfg file to run an HVM RHEL 4 (on Debian Etch, Xen 3.0.3)?

Also - is there a way to run RHEL 4 i386 under Xen on an x86_64 host (and be presented as a i386 machine to its processes)? One of the things I tried was to start an HVM install but I just couldn't make it go. The only way i could make it run was using Qemu.

Attempting to run a jailtime i386 image on an x86_64 machine created a weird "Chimera" where the packages that came from jailtime's image ran fine but any execution of "yum" insisted on bringing in i686 packages (even after tweaking yum's config), so I couldn't install any additional packages on it.
