Then we set metadata for this aggregate with host=openstack-node. Available only for Octavia minor version 2.14 or later. When you provision resources, you specify from which availability zone you want your instance to be built. Conflicts with availability_zone. Higher-level zones (i.e., that don't have hosts) will aggregate the results of their child zones. Very generally speaking, the L2 agent is primarily . Cloud users, cloud administrators, and the Compute service can pass metadata to instances: AggregateList. Ensures Compute metadata is read correctly. Setting Nova Availability Zones.

First, go to the Infrastructure > Clouds section and click + ADD. The scheduler then communicates with the openstack-cinder-volume . Changing this creates a new server. *if* forced_host is None and availability_zone not in \ available_zones: msg = _('The requested availability zone is not available') *raise* exception.InvalidRequest(msg) filter_properties = scheduler_utils.build_filter_properties( scheduler_hints . You might already have this collection installed if you are using the ansible package. A host can be in different aggregates. Backup procedures as mentioned in the document are followed/scheduled periodically. Nova is a way for openstack to provide computing instances (also known as virtual server). In a single datacenter deployment, the availability zones may be different racks. This AZ is only shown when listing the availability zones as an admin. The command returns the ID of the newly created aggregate. Not all cloud instances are born equal. In addition, it makes migrating between OpenStack deployments or concepts like multi-site OpenStack much simpler.

For the default password plugin, this would contain auth_url, username, password, project_name and any information about domains (for example, user_domain_name or project_domain_name) if the cloud supports them.For other plugins, this param will need to contain whatever parameters that auth plugin requires.

This spec aims to address three main problems: Congress is not currently able to provide high query throughput because all queries are handled by a single, single-threaded policy engine instance.
