I thought they would appreciate the higher priority ;)

gvt currently doesn't have anyway for it to determine the relative
priority of its guest vs the host, so if we set it too low we impact the
qos of the guest, too high and its affects the qos of the host. Keeping
it at max user though still gives the kernel some leeway to usurp it.
And who knows one day we may get a scheduler.
