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
