Procedure 2.3. To view and update default quota values

1. List all default quotas for all tenants, as follows:

   $ nova quota-defaults

   For example:

   $ nova quota-defaults
   +-----------------------------+-------+
   | Quota                       | Limit |
   +-----------------------------+-------+
   | instances                   | 10    |
   | cores                       | 20    |
   | ram                         | 51200 |
   | floating_ips                | 10    |
   | fixed_ips                   | -1    |
   | metadata_items              | 128   |
   | injected_files              | 5     |
   | injected_file_content_bytes | 10240 |
   | injected_file_path_bytes    | 255   |
   | key_pairs                   | 100   |
   | security_groups             | 10    |
   | security_group_rules        | 20    |
   +-----------------------------+-------+

2. Update a default value for a new tenant, as follows:

   $ nova quota-class-update --key value default

   For example:

   $ nova quota-class-update --instances 15 default

Procedure 2.4. To view quota values for an existing tenant (project)

1. Place the tenant ID in a useable variable, as follows:

   $ tenant=$(keystone tenant-list | awk '/tenantName/ {print $2}')

2. List the currently set quota values for a tenant, as follows:

   $ nova quota-show --tenant $tenant

   For example:

   $ nova quota-show --tenant $tenant
   +-----------------------------+-------+
   | Quota                       | Limit |
   +-----------------------------+-------+
   | instances                   | 10    |
   | cores                       | 20    |
   | ram                         | 51200 |
   | floating_ips                | 10    |
   | fixed_ips                   | -1    |
   | metadata_items              | 128   |
   | injected_files              | 5     |
   | injected_file_content_bytes | 10240 |
   | injected_file_path_bytes    | 255   |
   | key_pairs                   | 100   |
   | security_groups             | 10    |
   | security_group_rules        | 20    |
   +-----------------------------+-------+

Procedure 2.5. To update quota values for an existing tenant (project)

1. Obtain the tenant ID, as follows:

   $ tenant=$(keystone tenant-list | awk '/tenantName/ {print $2}')

2. Update a particular quota value, as follows:

   # nova quota-update --quotaName quotaValue tenantID

   For example:

   # nova quota-update --floating-ips 20 $tenant
   # nova quota-show --tenant $tenant
   +-----------------------------+-------+
   | Quota                       | Limit |
   +-----------------------------+-------+
   | instances                   | 10    |
   | cores                       | 20    |
   | ram                         | 51200 |
   | floating_ips                | 20    |
   | fixed_ips                   | -1    |
   | metadata_items              | 128   |
   | injected_files              | 5     |
   | injected_file_content_bytes | 10240 |
   | injected_file_path_bytes    | 255   |
