Re: [libvirt] [PATCH v6 2/2] blockcommit: turn on active commit

With this in place, I can (finally!) now do: virsh blockcommit $dom vda --shallow --verbose --pivot and watch qemu shorten the backing chain by one, followed by libvirt automatically updating the dumpxml output, effectively undoing the work of virsh snapshot-commit --no-metadata --disk-only. Commit is SOOOO much faster than blockpull, when I'm still fairly close in time to when the temporary qcow2 wrapper file was created via a snapshot operation! * src/qemu/qemu_driver.c (qemuDomainBlockCommit): Implement live commit.
