Hello all,
I've been digging around on this for a few days and I have not come up with a solution.
I have a Compaq ProLiant DL580 (G1, the old tan Compaq) with 4 x 700MHz P-III CPUs and 11GB of memory. I've loaded CentOS 5.5 with Virtualization (Xen) + KVM and patched up to current (full KS packages file list at the end).
When it boots, Xen only detects a single CPU as shown in the xm dmesg output (full output and the end):
(XEN) Detected 701.650 MHz processor. (XEN) I/O virtualisation disabled (XEN) CPU0: Intel Pentium III (Cascades) stepping 04 (XEN) Platform timer overflows in 2 jiffies. (XEN) Platform timer is 1.193MHz PIT (XEN) Brought up 1 CPUs [...] (XEN) Dom0 has maximum 1 VCPUs
The system shows all 4 CPUs when booted outside of Xen.
Any ideas on Xen options or anything I can try to see if I can get all 4 CPUs?
Thanks,
Bryan

Well, I can't say for sure the reason why it doesn't see all cpus, but I do know a P-III system is not going to support virtualization technology, so you would never be able to run windows guests on it. Only systems sold in the last year or two support VT. And motherboards that do support it are fairly cheap - starting in the $60 range.
Anywho, have you tried KVM instead?

Not looking to run Windows guests... so no problem there. And a free server beats $60 any day :-)
By the way, I have another one that is just about the same (4 x P-III 900Mhz and 16GB) running ESXi 3.5 U5 like a champ with no problems, so I was hoping to get Xen up on this one (for a project I need to test out Xen with).
And no, I have not explored KVM on there yet... even though I did load it. I'm really just interested in Xen right now.

Ok... figured it out.
Short answer: Rookie mistake.
Longer answer: the old-style Compaq BIOS was set for Operating System = Other rather than for UNIX/Linux. So APIC and SMP were disabled.
In case if helps anyone, below is the working 4 processor SMP output from xm dmesg. The system ain't fast, but it was free (and its not clogging a landfill somewhere).
Thanks,
Bryan

Like you just wrote yourself.. this system doesn't have VT - so can't use KVM.
