[Qemu-devel] [PATCH v2 0/4] compressed block-stream

Posted by Anton Nefedov 6 years, 5 months ago

v2:
  - 1st patch omitted (applied to 2.11)
  - remarks applied

v1: http://lists.nongnu.org/archive/html/qemu-devel/2017-11/msg02515.html

It might be useful to compress images during block-stream;
this way the user can merge compressed images of a backing chain and
the result will remain compressed.

Anton Nefedov (3):
  block: support compressed write for copy-on-read
  block-stream: add compress option
  iotests: 030: add compressed block-stream test

Pavel Butsykin (1):
  qcow2: multiple clusters write compressed
