Re: [libvirt] [PATCHv3 30/36] qemu: monitor: Add argument for specifying backing name for block commit

To allow changing the name that is recorded in the overlay of the TOP image used in a block commit operation, we need to specify the backing name to qemu. This is done via the "backing-file" attribute to the block-commit commad.
