      Target Path

      Enter the location to mount the source device for the storage pool in the Target Path field. If the location does not already exist, virt-manager will create the directory.

      Format

      Select a format from the Format list. The device is formatted with the selected format.

      This example uses the ext4 file system, the default Red Hat Enterprise Linux file system.

      Source Path

      Enter the device in the Source Path field.

      This example uses the /dev/sdc1 device.

      Verify the details and press the Finish button to create the storage pool.

3. Verify the new storage pool

   The new storage pool appears in the storage list on the left after a few seconds. Verify the size is reported as expected, 458.20 GB Free in this example. Verify the State field reports the new storage pool as Active.
   Select the storage pool. In the Autostart field, click the On Boot check box. This will make sure the storage device starts whenever the libvirtd service starts.
