Re: [libvirt] [PATCHv8 03/11] blockjob: add qemu capabilities related to block jobs

Upstream qemu 1.3 is adding two new monitor commands, 'drive-mirror' and 'block-job-complete'[1], which can drive live block copy and storage migration. Additionally, RHEL 6.3 had backported an earlier version of most of the same functionality, but under the names '__com.redhat_drive-mirror' and '__com.redhat_drive-reopen' and with slightly different JSON arguments, which we can support without too much extra effort.
