Here you remove auto-adding of the mouse for all drivers, but only re-add it
to the QEMU driver, leading to failures in sexpr2xmltest.

Hmm, if non-USB input devices get skipped when generating the command line and
when formatting the XML, I wonder why are we adding it there in the first place.

os.type has to be "hvm" in the qemu driver.
