How are the RedHat CD's labeled? We have 3 Altix machines running
ProPack 3 (which is based on RHEL 3). Apparently yours would be running
ProPack 4 since they've decided to shift to SuSE. I'm curious if they
provided you with ProPack 3 CD's but pre-installed the PP4 OS on the
machine.

Just glancing at the docs for Xen, it looks pretty x86-specific
(especially considering the mention of them working on a "port" to
x86-64). There isn't really a "32-bit mode" on Itanium. You can run
32-bit binaries, but the CPU's emulate the 32-bit instructions. We've
safely run some code, but it's always preferable to go with a pure 64-
bit solution.
