For tenants, quota controls are available to limit the (flag and default shown in parenthesis):
Number of volumes which may be created (volumes=10)
Total size of all volumes within a project as measured in GB (gigabytes=1000)
Number of instances which may be launched (instances=10)
Number of processor cores which may be allocated (cores=20)
Publicly accessible IP addresses for persistence in DNS assignment (floating_ips=10)
Privately (or publicly) accessible IP addresses for management purposes (fixed_ips=-1 unlimited)
Amount of RAM that can be allocated in MB (ram=512000)
Number of files that can be injected (injected_files=5)
Maximal size of injected files in B (injected_file_content_bytes=10240)
Number of security groups that may be created (security_groups=10)
Number of rules per security group (security_group_rules=20)
The defaults may be modified by setting the variable in
nova.conf, then restarting the nova-api
service.
To modify a value for a specific project, the nova-manage command should be used. For example:
$ nova-manage project quota --project=1113f5f266f3477ac03da4e4f82d0568 --key=cores --value=40
Alternately, quota settings are available through the OpenStack Dashboard in the "Edit Project" page.
