I''ve just got a bit of a funny with a quad CPU Opteron box running Xen 3.0.2 on SuSE 10.1. One of the CPUs failed so I was down to 3 CPUS and everything ran OK, but having just added the replacement, when booting the Xen kernel, /proc/cpuinfo and top etc. only report CPU0 and CPU3. If I boot the standard kernel, all four CPUs show up. xm dmesg also reports 4 CPUs started and xm top says there are 4 VCPUs available to dom0. Any thoughts?

Hi! I`m with the same problem! I have 4 processors, but my /proc/cpuinfo just show 1!

Surely, you didn''t compile Xen for SMP... Or the Dom0 kernel (less likely). -- Mats ________________________________ From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Rodrigo Lord Sent: 14 August 2006 13:47 To: Matthew Wild; xen-users@lists.xensource.com Subject: Re: [Xen-users] Missing CPUs Hi!
