33 ration tools, such as targetcli. Part of doing this will be entering a
34 handler-specific configuration string.

36 CONFIGURING GLUSTER HANDLER (glfs)
37 This handler uses the Gluster glfs API to use Gluster as a backstore
38 for the image file.

40 Its configuration string is:
41
42 volume@hostname/filename
43 volume: The volume on the Gluster server
44 hostname: The server's hostname
45 filename: The backing file
46
47 CONFIGURING QCOW HANDLER (qcow)
48 This handler supports qcow, qcow2, or raw image file formats.
49
50 Its configuration string is:
51
52 path
53 path: The full path to a file of a supported file format. The file
54 must already have been created using qemu-img.
