[libvirt] [PATCH V3 0/2] storagevol: add 'nocow' option to vol xml

[Chunyan Liu]

Add 'nocow' option to vol xml, so that user can have a chance to create
a volume with NOCOW flag set on btrfs. It improves performance when the
volume is a file image on btrfs and is used in VM environment.

Changes:
  * fix typo in V2
  * add test case for 'nocow', in separate patch
