From: Sam Eiderman <shmuel.eiderman@xxxxxxxxxx>
Add QTest tests to check the logical geometry override option.
The tests in hd-geo-test are out of date - they only test IDE and do not
test interesting MBRs.
Creating qcow2 disks with specific size and MBR layout is currently
unused - we only use a default empty MBR.
