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.
Todo
At some point, probably in Queens, we need to scrub this page and mention the microversions that remove the proxy and network-related resource quotas.
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. |

| security-group-rules | Number of security group rules per project. |
| server-groups | Number of server groups per project. |

View and update Compute quotas for a project¶
To view and update default quota values¶
List all default quotas for all projects:
$ openstack quota show --default +----------------------+----------+ | Field | Value | +----------------------+----------+ | backup-gigabytes | 1000 | | backups | 10 | | cores | 20 | | fixed-ips | -1 | | floating-ips | 50 | | gigabytes | 1000 | | health_monitors | None | | injected-file-size | 10240 | | injected-files | 5 | | injected-path-size | 255 | | instances | 10 | | key-pairs | 100 | | l7_policies | None | | listeners | None | | load_balancers | None | | location | None | | name | None | | networks | 10 | | per-volume-gigabytes | -1 | | pools | None | | ports | 50 | | project | None | | project_name | project | | properties | 128 | | ram | 51200 | | rbac_policies | 10 | | routers | 10 | | secgroup-rules | 100 | | secgroups | 10 | | server-group-members | 10 | | server-groups | 10 | | snapshots | 10 | | subnet_pools | -1 | | subnets | 10 | | volumes | 10 | +----------------------+----------+
Note
This lists default quotas for all services and not just nova.
Update a default value for a new project, for example:
$ openstack quota set --instances 15 --class default
To view quota values for an existing project¶
List the currently set quota values for a project:
$ openstack quota show PROJECT_NAME +----------------------+----------------------------------+ | Field | Value | +----------------------+----------------------------------+ | backup-gigabytes | 1000 | | backups | 10 | | cores | 32 | | fixed-ips | -1 | | floating-ips | 10 | | gigabytes | 1000 | | health_monitors | None | | injected-file-size | 10240 | | injected-files | 5 | | injected-path-size | 255 | | instances | 10 | | key-pairs | 100 | | l7_policies | None | | listeners | None | | load_balancers | None | | location | None | | name | None | | networks | 20 | | per-volume-gigabytes | -1 | | pools | None | | ports | 60 | | project | c8156b55ec3b486193e73d2974196993 | | project_name | project | | properties | 128 | | ram | 65536 | | rbac_policies | 10 | | routers | 10 | | secgroup-rules | 50 | | secgroups | 50 | | server-group-members | 10 | | server-groups | 10 | | snapshots | 10 | | subnet_pools | -1 | | subnets | 20 | | volumes | 10 | +----------------------+----------------------------------+
Note
This lists quotas for all services and not just nova.
To update quota values for an existing project¶
Obtain the project ID.
$ project=$(openstack project show -f value -c id PROJECT_NAME)
Update a particular quota value.
To update quotas for a project:
$ openstack quota set --QUOTA_NAME QUOTA_VALUE PROJECT_NAME
To update quotas for a class:
$ openstack quota set --class --QUOTA_NAME QUOTA_VALUE CLASS_NAME
Note
Only the
defaultclass is supported by nova.For example:
$ openstack quota set --instances 50 PROJECT_NAME $ openstack quota show PROJECT_NAME +----------------------+----------------------------------+ | Field | Value | +----------------------+----------------------------------+ | ... | ... | | instances | 50 | | ... | ... | +----------------------+----------------------------------+
Note
To view a list of options for the openstack quota set command, run:
$ openstack help quota set
View and update Compute quotas for a project user¶
To view quota values for a project user¶
Place the user ID in a usable variable.
$ projectUser=$(openstack user show -f value -c id USER_NAME)
Place the user’s project ID in a usable variable, as follows:
$ project=$(openstack project show -f value -c id PROJECT_NAME)
List the currently set quota values for a project user.
$ nova quota-show --user $projectUser --tenant $project
For example:
$ nova quota-show --user $projectUser --tenant $project +-----------------------------+-------+ | 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 | | key_pairs | 100 | | security_groups | 10 | | security_group_rules | 20 | | server_groups | 10 | | server_group_members | 10 | +-----------------------------+-------+
To update quota values for a project user¶
Place the user ID in a usable variable.
$ projectUser=$(openstack user show -f value -c id USER_NAME)
Place the user’s project ID in a usable variable, as follows:
$ project=$(openstack project show -f value -c id PROJECT_NAME)
Update a particular quota value, as follows:
$ nova quota-update --user $projectUser --QUOTA_NAME QUOTA_VALUE $project
For example:
$ nova quota-update --user $projectUser --floating-ips 12 $project $ nova quota-show --user $projectUser --tenant $project +-----------------------------+-------+ | Quota | Limit | +-----------------------------+-------+ | instances | 10 | | cores | 20 | | ram | 51200 | | floating_ips | 12 | | 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 | | server_groups | 10 | | server_group_members | 10 | +-----------------------------+-------+
Note
To view a list of options for the nova quota-update command, run:
$ nova help quota-update
To display the current quota usage for a project user¶
Use nova limits to get a list of the current quota values and the current quota usage:
$ nova limits --tenant PROJECT_NAME
+------+-----+-------+--------+------+----------------+
| Verb | URI | Value | Remain | Unit | Next_Available |
+------+-----+-------+--------+------+----------------+
+------+-----+-------+--------+------+----------------+
+--------------------+------+-------+
| Name | Used | Max |
+--------------------+------+-------+
| Cores | 0 | 20 |
| Instances | 0 | 10 |
| Keypairs | - | 100 |
| Personality | - | 5 |
| Personality Size | - | 10240 |
| RAM | 0 | 51200 |
| Server Meta | - | 128 |
| ServerGroupMembers | - | 10 |
| ServerGroups | 0 | 10 |
+--------------------+------+-------+
Note
The nova limits command generates an empty table as a result of the Compute API, which prints an empty list for backward compatibility purposes.
