[fedora-virt] performance regressions in Fedora 13?

[Kenneth Armstrong]

Thanks Rich,

I do have kvm_intel loaded, and I did verify that I'm using kvm as the
hypervisor and not qemu.

Something that occured to me is that I am using BTRFS with Fedora 13
instead of EXT4, which is what I was using under F11.  I was under the
impression that BTRFS was actually a bit quicker than EXT4 though.

I do have SELinux enabled, but I'm not getting any AVC warnings.
