Manage Compute service quotas¶

As an administrative user, you can use the nova quota-* commands, which are provided by the python-novaclient package, to update the Compute service quotas for a specific project or project user, as well as update the quota defaults for a new project.

Compute quota descriptions

Quota name	Description
cores	Number of instance cores (VCPUs) allowed per project.
fixed-ips	Number of fixed IP addresses allowed per project. This number must be equal to or greater than the number of allowed instances.
floating-ips	Number of floating IP addresses allowed per project.
injected-file-content-bytes	Number of content bytes allowed per injected file.
injected-file-path-bytes	Length of injected file path.
injected-files	Number of injected files allowed per project.
instances	Number of instances allowed per project.
key-pairs	Number of key pairs allowed per user.
metadata-items	Number of metadata items allowed per instance.
ram	Megabytes of instance ram allowed per project.
security-groups	Number of security groups per project.
security-group-rules	Number of rules per security group.
server-groups	Number of server groups per project.
server-group-members	Number of servers per server group.

View and update Compute quotas for a project (project)¶

To view and update default quota values¶

List all default quotas for all projects:

$ 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    |

+-----------------------------+-------+

Update a default value for a new project.

$ nova quota-class-update --KEY VALUE default

For example:

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

To view quota values for an existing project¶

Place the project ID in a usable variable.

$ tenant=$(openstack project show -f value -c id TENANT_NAME)

List the currently set quota values for a project.

$ nova quota-show --tenant $tenant

For example:

$ nova quota-show --tenant $tenant
+-----------------------------+-------+
| Quota                       | Limit |

Obtain the project ID.

$ tenant=$(openstack project show -f value -c id TENANT_NAME)

Update a particular quota value.

For example:

$ nova quota-update --floating-ips 20 $tenant
