Datastore name associated with the ``vmware_datacenter_path``
* ``vmware_datastores``
Optional. Default: Not set.
This option can only be specified in configuration file and is specific
to the VMware storage backend.
vmware_datastores allows administrators to configure multiple datastores to
save glance image in the VMware store backend. The required format for the
option is: <datacenter_path>:<datastore_name>:<optional_weight>.
where datacenter_path is the inventory path to the datacenter where the
datastore is located. An optional weight can be given to specify the priority.
Example::
vmware_datastores = datacenter1:datastore1
vmware_datastores = dc_folder/datacenter2:datastore2:100
vmware_datastores = datacenter1:datastore3:200
**NOTE**:
- This option can be specified multiple times to specify multiple datastores.
- Either vmware_datastore_name or vmware_datastores option must be specified
in glance-api.conf
- Datastore with weight 200 has precedence over datastore with weight 100.
- If no weight is specified, default weight '0' is associated with it.
- If two datastores have same weight, the datastore with maximum free space
will be chosen to store the image.
- If the datacenter path or datastore name contains a colon (:) symbol, it
must be escaped with a backslash.
* ``vmware_api_retry_count=TIMES``
Optional. Default: ``10``
