Subject: [PATCH] block/vmdk: Support creation of SCSI VMDK images in qemu-img
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Signed-off-by: Ulrich Hecht <uli@suse.de>
[AF: Changed BLOCK_FLAG_SCSI from 8 to 16 for v1.2]
[AF: Rebased onto upstream VMDK SCSI support]
[AF: Rebased onto skipping of image creation in v1.7]
[AF: Simplified in preparation for v1.7.1/v2.0]
