It's a Centos6 "minimal" guest on a Centos 6 "Desktop" host so technically 
this shouldn't be needed but I tried it anyway without effect. I also 
removed the NIC and tried playing with the APIC/ACPI settings but this 
doesn't seem to matter either. I filed a bug here:

http://bugs.centos.org/view.php?id=5028

According to toracat he sees this also on RHEL6 and SL6 which has me 
worried because if this is really a Problem upstream that hasn't been 
addressed yet then I'm not sure how I can justify using Centos 6 as a 
virtualization platform. 10% of wasted resources per VM is simply not 
acceptable when you run more than one guest on a system.
