The Virtuozzo Storage driver is a fault-tolerant distributed storage
system that is optimized for virtualization workloads.
Set the following in your cinder.conf file, and use the following
options to configure it.
volume_driver = cinder.volume.drivers.vzstorage.VZStorageDriver
| Configuration option = Default value | Description |

vzstorage_default_volume_format = raw |
(String) Default format that will be used when creating volumes if no volume format is specified. |
vzstorage_mount_options = None |
(List) Mount options passed to the vzstorage client. See section of the pstorage-mount man page for details. |
vzstorage_mount_point_base = $state_path/mnt |
(String) Base dir containing mount points for vzstorage shares. |
vzstorage_shares_config = /etc/cinder/vzstorage_shares |
(String) File with the list of available vzstorage shares. |
vzstorage_sparsed_volumes = True |
