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.

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.
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 security group rules per project.
server-groups	Number of server groups per project.
server-group-members	Number of servers per server group.

Update a default value for a new project, for example:
```
$ openstack quota set --instances 15 --class default
```

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 default class is supported by nova.

For example:

$ openstack quota set --instances 50 PROJECT_NAME
$ openstack quota show PROJECT_NAME

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

$ 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

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.
