Virsh domblklist

virsh domblklist domain [--inactive] [--details] Print a table showing the brief information of all block devices associated with domain. If --inactive is specified, query the block devices that will be used on the next boot, rather than those currently in use by a running domain. If --details is specified, disk type and device value will also be printed. Other contexts that require a block device name (such as domblkinfo or snapshot-create for disk snapshots) will accept either target or unique source names printed by this command.
