I've used it reliably since 2.7 though until the recent patch I had to 
add a virtio input device for keyboard and mouse in addition to the 
built in PS/2 device. Looking at the patch I guess that worked because 
virtio has much better buffering. I might keep it though as it's more 
likely to be immune to windows update and I swear that is out to get me.

Definitely the approach to recommend. No ctrl-alt-backspace getting 
redirected to your host X server or losing focus on the host to a dialog 
and so losing input. Beyond essential if you've got a single monitor or 
are using fullscreen applications such as games where the mouse needs 
it's own scale / boundary constraints.
