Nova Quota is used to manage operational limits for projects. Currently,
|
|
this resource can manage Nova's quotas for:
|
|
- cores
|
|
- fixed_ips
|
|
- floating_ips
|
|
- instances
|

- injected_files

|
- security_groups

|
- security_group_rules
|
|
- server_groups
|
|
- server_group_members
|
|
|
|
Note that default nova security policy usage of this resource
|
|
is limited to being used by administrators only. Administrators should be
|
|
careful to create only one Nova Quota resource per project, otherwise
|
|
it will be hard for them to manage the quota properly.
