[Qemu-devel] [PATCH v2 0/2] qcow2: include LUKS payload overhead in qemu-img measure

Posted by Stefan Hajnoczi 6 years, 9 months ago

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.
