红帽全球峰会5.5.6.6. 配额
配额可用于限制项目可用的网络资源数量。您可以为所有项目实施默认配额。要查看配额选项，请参阅 /var/lib/config-data/puppet-generated/neutron/etc/neutron/neutron.conf。
OpenStack 网络还通过配额扩展 API 支持每个项目配额限制。要启用每个项目配额，您必须在 /var/lib/config-data/puppet-generated/neutron/etc/neutron/neutron.conf 中设置 quota_driver 选项。例如：
quota_driver = neutron.db.quota_db.DbQuotaDriver
quota_driver = neutron.db.quota_db.DbQuotaDriver
