Re: [libvirt] [PATCH 2/2] util: storage: add JSON backing volume parser 'raw' block driver

The 'raw' block driver in Qemu is not directly interesting from libvirt's perspective, but it can be layered above some other block drivers and this may be interesting for the user. The patch adds support for the 'raw' block driver. The driver is treated simply as a pass-through and child driver in JSON is queried to get the necessary information.
