Attaching a File-Based Storage Volume
Shut down the guest before attaching the disk. Note that is also possible to add the device while the guest is running, see virsh man page for more details.
Provision the storage volume as described here: [[]]
The command requires at minimum the file-based storage volume path, as shown by the virsh vol-list command, and the device name under which the disk is exposed to guest, typically "vdX", where X is "a", "b", etc.
virsh attach-disk testvm-01 /main-storage-pool/test-volume vdb --config
virsh will detect malformed device names and will error out if that is the case.
