/proc/cpuinfo on a Dell 6650 shows the machine as having 8 CPUs
(numbered 0 through 7). Its running AS version 3 and kernel is
2.4.21-27.ELsmp

The machine has the maximum of 4 CPUs actually. Is this a bug or am I
not reading the file correctly?

Thanks for any leads

We recently picked up a new SGI Altix 350 (2 bricks, 4 cpus, 4GB) for
"playing around", although it will hopefully become a part of our
corporate development environment.  It came installed with SuSE 9 SLES
(which I'm not very fond of) and some Red Hat Enterprise for Itanium
CDs, which I'd like to install in it.  I'd like to do some sort of
virtualization, a la Xen, to allocate virtual systems to various
developers, but I'm not finding much that will run on the Altix 350 in
32-bit mode with SMP, much less ia64.

Has anyone run Xen on *any* flavor of Linux running on Altix (in
particular, Red Hat/Fedora-based)?  Any suggestions or ideas?

I went to a couple of Xen presentations at the Red Hat Summit in early
June.  The comment there was that x86 32bit was mostly working now but
that x86_64, ia64, amc ppc64 were "still in flux".

Rik van Riel also said that Xen 3.0 was "not stable yet but in Fedora
Core 4".  He expected 1-2 months for a feature freeze and 3-4 months
before it got stable.

Intel has 30 developers working on Xen according to the Intel keynote.

I don't know if VMware supports the ia64 yet - from a quick look at
their web site, they didn't in VMware 4 but they're not really saying if
it's supported in VMware 5.

There is a mailing list for Xen discussions - you could try there.
