Development version of OpenNebula 4.4. The material on this page needs to be reviewed for completeness and accuracy.
Datastores can be parametrized with several parameters. In the following list there are the meaning of the different parameters for all the datastores.
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
