[PATCH v10 0/2] qcow2: add zstd cluster compression

Posted by Vladimir Sementsov-Ogievskiy 4 years, 3 months ago

Hi all!

Here is my proposal, about how to correctly update qcow2 specification
to introduce new field, keeping in mind currently existing images and
downstream Qemu instances.

v10: Spelling/structure improvements by Max

v9: Merge 01 and 02
    Change wordings
    Require header alignment

Vladimir Sementsov-Ogievskiy (2):
  docs: improve qcow2 spec about extending image header
  docs: qcow2: introduce compression type feature
