Re: [PATCH 0/4] qemu: Report stats for backing images

Management tools such as oVirt need to monitor the 'allocation' of the backup job scratch file or disk copy target. Add the stats to the bulk stats. The stats can be queried by: $ virsh domstats $VM --block --backing Patch 1 fixes a bug in the status XML formatter where we'd not store the private data for the scratch file of a backup job, which resulted in a failure of getting the stats after restart of libvirtd.
