[libvirt] [PATCHv1 00/13] Support qcow2 features in external snapshots



https://bugzilla.redhat.com/show_bug.cgi?id=980327

First ten patches contain no functional change.

Patches 11 and 12 potentially change the default qcow2 compatibility
level.

The last patch contains the proposed XML.

Ján Tomko (13):
  Visually separate snapshot disk subelements
  Remove feature formating funcs from pool-specific options
  Separate out virStorageFeatureParse
  Separate virStorageFeatureFormat
  Split out storage format 'compat' attribute sanity check
  Use XPath when parsing snapshot disk definition
  Rename virStorageBackendCreateQemuImgCmd
  Introduce struct _virStorageBackendQemuImgInfo
  Split out qemu-img command generation
  Remove overengineered loop
  Use qemu-img to precreate the qcow2 disks
  Rework qemu-img command generation for inactive external snapshots
  Add qcow2 features to snapshot XML
