I made a test on 4.3.0-rc6, spice without qxl works well
for win7 now, whileeven spice without qxl will cause qemu upstream crash
before 4.3.0-rc6 .
By the way , my self-compiled qemu upstream work well
with qxl, it's really strange.

Actually, SPICE support is indeed there, it is _only_ qxl support that
was causing the crash and that has been reverted by the said commit.
