libvirt used improper seperator (comma) of "lvs", as if there is striped lvm volume exists, the output of "device" field will use "comma" to seperate the multiple device paths. This cause the regular expression used in the codes to parse the "lvs" output doesn't work normally anymore.
Any logical pool creation will fail if it has striped logical volume. Also libvirt doesn't have right mechnism to format
multiple <device> XML (with <extents>) for the multiple device paths of striped volume.
Use different seperator (#), and write new codes to parse the multiple device paths of striped volume, and format multiple <devices> XML.
Users are able to create logical pool contains striped volume, and get proper XML for the striped volume.
