[Qemu-devel] [PATCH v3 0/2] qcow2: include LUKS payload overhead in qemu-img measure

[Stefan Hajnoczi <stefanha@redhat.com>]

v3:
 * Use encrypt.iter-time=10 to speed up qemu-iotests 178 [Max]
v2:
 * Take into account all "encrypt." image creation options since the LUKS
   payload size varies depending on the cipher [Max]

The LUKS payload has a significant size (>1 MB).  It must be included in the
qemu-img measure calculation so we arrive at the correct minimum image size.
