It's possible to use Virtual Storage provided by Cinder for Virtual Machine Instance.
This example shows to set to use GlusterFS for Virtual Storage.

| [1] |
Configure GlusterFS Server in your LAN first.
This example uses a replication volume "/vol01" provided by "gfs01" and "gfs02". |
| [2] | Install some packages first. |
