[PATCH 0/5] parallels: load bitmap extension

Posted by Vladimir Sementsov-Ogievskiy 4 years, 9 months ago

Hi all!

Suddenly we need to load bitmaps from parallels image in our product.
So here is a feature.

Vladimir Sementsov-Ogievskiy (5):
  qcow2-bitmap: make bytes_covered_by_bitmap_cluster() public
  parallels.txt: fix bitmap L1 table description
  parallels: support bitmap extension for read-only mode
  iotests.py: add unarchive_sample_image() helper
  iotests: add parallels-read-bitmap test
