Subject: [PATCH] v2v: -oa preallocated for qcow2 output now fully allocates
ffd6ed
 the file (RHBZ#1251909).
ffd6ed
ffd6ed
When the output format is qcow2 and -oa preallocated is used,
ffd6ed
previously it would only allocate the metadata.  That was a regression
ffd6ed
over previous behaviour of virt-v2v 0.9.  Change it so it allocates
ffd6ed
the full file size in this case.
ffd6ed
ffd6ed
(cherry picked from commit 42b6bb12dcbc5103044a9099d71f17a82009e7de)
