Re: [Xen-users] Load Average 1.00 at idle

I noticed this too, but I did not install any SMP kernel packages at all.

   # rpm -qa  | grep kernel | sort
   kernel-2.6.11-1.1369_FC4
   kernel-2.6.12-1.1398_FC4
   kernel-2.6.12-1.1447_FC4

   kernel-xen0-devel-2.6.12-1.1398_FC4
   kernel-xen0-devel-2.6.12-1.1447_FC4

   kernel-xenU-2.6.12-1.1398_FC4_lvm_md_fix.agoode
   kernel-xenU-2.6.12-1.1447_FC4
   kernel-xenU-devel-2.6.12-1.1398_FC4
   kernel-xenU-devel-2.6.12-1.1447_FC4


And you might have noticed that I typod the kernel for dom0 in the original post. Obviously, it is not a xenU kernel in dom0. But it does still say SMP.

   Linux 2.6.12-1.1447_FC4xen0 #1 SMP Fri Aug 26 21:13:28 EDT 2005 i686

Here are some details about the system.

In my experience, the previous Xen, running the 1398 FC4 Xen kernels did not have this behavior? Any ideas on what can be done to get my 'real' load averages back?

You have an SMP kernel but are running what I am guessing is a UP
Celeron.
