The only ones remaining are some real crufty SVGs and references to things that still exist because nova-network was once a thing. Change-Id: I1aebf86c05c7b8c1562d0071d45de2fe53f4588b Signed-off-by: Stephen Finucane <sfinucan@redhat.com>

Quotas
Nova uses a quota system for setting limits on resources such as number of instances or amount of CPU that a specific project or user can use.
Quota limits and usage can be retrieved using the command-line interface.
Types of quota
| Quota name | Description |
|---|---|
| cores | Number of instance cores (VCPUs) 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. |
| server_groups | Number of server groups per project. |
| server_group_members | Number of servers per server group. |
The following quotas were previously available but were removed in microversion 2.36 as they proxied information available from the networking service.
| Quota name | Description |
|---|---|
| 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. |
| networks | Number of networks allowed per project (no longer used). |
| security_groups | Number of security groups per project. |
| security_group_rules | Number of security group rules per project. |
Similarly, the following quotas were previously available but were removed in microversion 2.57 as the personality files feature was deprecated.
| Quota name | Description |
|---|---|
| injected_files | Number of injected files allowed per project. |
| injected_file_content_bytes | Number of content bytes allowed per injected file. |
| injected_file_path_bytes | Length of injected file path. |
Usage
Project quotas
To list all default quotas for projects, run:
$ openstack quota show --defaultNote
This lists default quotas for all services and not just nova.
For example:
$ openstack quota show --default

+----------------------+----------------------------------+To view a list of options for the openstack quota show command, run:
$ openstack quota show --helpUser quotas
Note
User-specific quotas are legacy and will be removed when migration to
unified limits </admin/unified-limits.html>
is complete. User-specific quotas were added as a way to provide
two-level hierarchical quotas and this feature is already being offered
in unified limits. For this reason, the below commands have not and will
not be ported to openstackclient.
To list the quotas for your user, run:
$ nova quota-show --user USER --tenant PROJECTwhere USER is the ID or name of your user and
PROJECT is the ID or name of your project. For example:
$ nova quota-show --user $OS_USERNAME --tenant $OS_PROJECT_ID
