Public bug reported:
The recent upgrade to kvm is slowing down kvm access considerably. It
gives comparable performance to running kvm with no kernel modules,
however I do have kvm and kvm_intel loaded.
I'm in the kvm group and am running kvm like this:
$ kvm -hda ubuntu_13.04.kvm -name "ubuntu_13.04.kvm" -m 512 -net
user -net nic -redir tcp:11601::22 -serial file:/tmp/kvm.log
