[Qemu-devel] [RFC PATCH 00/16] qcow2: Basic version 3 support


From: Kevin Wolf
Subject: [Qemu-devel] [RFC PATCH 00/16] qcow2: Basic version 3 support
Date: Tue, 27 Mar 2012 17:03:19 +0200

While this is not quite ready to be merged, I think the important stuff is done
and works (it survives qemu-iotests at least) and probably now is the right
time to start getting feedback. I'm going to get this merged before the 1.1
soft freeze.

What's left is probably some cleanup, adding more new test cases and obviously
fixing whatever bugs come up.

Kevin Wolf (15):
  Specification for qcow2 version 3
  qcow2: Ignore reserved bits in get_cluster_offset
  qcow2: Ignore reserved bits in count_contiguous_clusters()
  qcow2: Fail write_compressed when overwriting data
  qcow2: Ignore reserved bits in L1/L2 entries
  qcow2: Refactor qcow2_free_any_clusters
  qcow2: Simplify count_cow_clusters
  qcow2: Ignore reserved bits in refcount table entries
  qcow2: Ignore reserved bits in check_refcounts
  qcow2: Version 3 images
  qcow2: Support reading zero clusters
  qcow2: Support for feature table header extension
  qemu-iotests: Test COW with zero clusters
  qcow2: Zero write support
  qemu-iotests: use qcow3

Paolo Bonzini (1):
  qemu-iotests: add a simple test for write_zeroes
