RESTRICTED_DIRS: Paths not allowed for image importing
SAFE_DIRS: Paths allowed for image importing
NO_DECOMPRESS: Do not decompress images downloaded
LIMIT_TRANSFER_BW: Maximum bandwidth used to download images. By default is bytes/second but you can use k, m and g for kilo/mega/gigabytes.
BRIDGE_LIST: List of hosts used for image actions. Used as a roundrobin list.
POOL_NAME: Name of the Ceph pool to use
VG_NAME: Volume group to use
BASE_IQN: iscsi base identifier
STAGING_DIR: Temporary directory where images are downloaded
DS_TMP_DIR: Temporary directory where images are downloaded
CEPH_HOST: Space-separated list of Ceph monitors.
CEPH_SECRET: A generated UUID for a LibVirt secret.
LIMIT_MB: Limit, in
MB, of storage that OpenNebula will use for this datastore
