Binary package hint: qemu-kvm

This seems to be a regression in the last week or two.

I've got Beta2 (64bit) booted on a 64bit host (upto date as of today
10th Apr).

The mouse is erm stuttering - it's a bit hard to describe but if I move the mouse slowly it will stop and a few seconds later
suddenly move quite a distance - probably to where it should have been if it had been following it all the time.

Neither the host or guest are doing anything much at the time, and I'm
pretty sure this didn't used to happen.

>From /var/log/libvirt/qemu/fiddle2.log:

This is on an i7-860 host.
