Hello!
I try to use KVM on slackware host and centos5 guest with SMP.
When the server is idle, I get following errors in /var/log/messages:

What does it mean?
The problem also reproduces without SMP or USB for a guest.
I have installed Debian 5.0.5 to another VM, and the problem is
unreproducible under it:
debian-5-x64:~# uname -a
Linux debian-5-x64.slave 2.6.26-2-amd64 #1 SMP Thu Aug 19 00:37:36 UTC
2010 x86_64 GNU/Linux
Should I post it to redhat bugzilla as redhat bug, or it is KVM bug?
Or post it to the CentOS bugzilla since you're not using Red Hat.
There's been various time related issues in RHEL5.x so my inclination
would be that it's not an upstream issue until you verify it with the
latest upstream.

Also, I have noticed a strange thing. In top on host, Debian qemu
process consumes nearly 1% of cpu, but CentOS qemu process consumes
nearly 20-30%, even when VM is idle.
The problem also reproduces on centos-i386 guest and doesn't reproduce
on debian-5-i386.
