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

["Michael J. Baysek" <mjbaysek@xxxxxxxxxx>]

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-devel-2.6.11-1.1369_FC4
   kernel-devel-2.6.12-1.1398_FC4
   kernel-devel-2.6.12-1.1447_FC4
   kernel-xen0-2.6.12-1.1398_FC4
   kernel-xen0-2.6.12-1.1398_FC4_lvm_md_fix.agoode
   kernel-xen0-2.6.12-1.1447_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
   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
   i686 i386 GNU/Linux
