I would have used virCommandAddArgFormat() instead of creating my own
temporary string here, but that's minor.
ACK; you fixed my concerns from the previous version.
Also, be sure you run 'make check'; somewhere between commit de29867 and
7022b09, you broke qemuhelptest (I'm assuming it will get fixed soon,
perhaps by this commit, so I'm not chasing which commit did the actual
breakage):

0x0000b0f2f1bffefff4cffd62fffddc6e, expected
