Well, apparently it's possible for a patch to sneak in through
review process and break 'make check'. It happened just lately
with 0e502466 which changed the default of vgamem_mb for
qxl device. However, there were left some domain XMLs within our
test suite relying on the old default. These should be updated to
match the change.
