It does that by reading the metadata information from an external

path, configurable through a configuration parameter

`filesystem_store_metadata_file` in glance-api.conf

BZ #9 79 14 2

Glance works as a registry for images. Each record is considered

an immutable resource that holds information about the image it

represents. In previous versions only one location could be

associated with one record. An image persisted in its location in

Glance.

With this enhancement, it is now possible to associate one record

to multiple locations. These locations can point to any enabled

store. This enhancement can eventually be used to configure

failover stores, which in turn would add High Availability

capabilities to Image services. For now, using multiple locations

for one records can be used to replicate images in different

stores.

BZ #9 82357

An enhancement has been made to support advanced features of

Neutron Security Groups. These groups have additional features,

such as direction, IP version, etc. that could not be set

previously when using the Dashboard to manage the rules.

Now, when using OpenStack Networking after updating the

appropriate Dashboard setting, the improved security groups rule

management is available.

The setting should be updated in /etc/openstack-

dashboard/local_settings:

Set 'enable_security_group' to True in the

OPENSTACK_NEUTRON_NETWORK key. (True is the package default).

BZ #9 85139

A feature has been added which provides basic quotas support for

OpenStack Image service (Glance). A storage quota has been added

that is applied against the sum total of a user's storage

consumption, across all configured storage systems. A single quota

is applied to all users via the configuration option

'total_storage_quota'.

BZ #9 854 54

Quality of service (QoS) is now configurable for Block Storage

volumes. This update provides a framework in Block Storage for

both front-end (Compute) and back-end (Block Storage) QoS based

on volume type and user-defined specifications. This feature is

managed with the Block Storage CLI 'cinder qos-*' commands.
