Overview

Quotas limit the number of networking resources a project can consume. Default quotas are set cluster-wide during deployment. You can override them per project to accommodate workloads that require higher limits or to restrict projects that should operate within a strict budget.
Administrator Access Required — This operation requires the admin role. Contact your Xloud administrator if you do not have sufficient permissions.
Prerequisites
  • Admin credentials sourced from admin-openrc.sh
  • The target project ID or name

​
View Current Quotas

Log in to the Xloud Dashboard (https://connect.<your-domain>) as an administrator and navigate to Admin → Identity → Projects. Select the project, then click Modify Quotas. Scroll to the Network section to review and update networking quotas.

​
Update Quotas for a Project

Navigate to Admin → Identity → Projects, select the project, click Modify Quotas, update the values in the Network section, and click Save.

​
Reset Quotas to Defaults

Reset project quotas to cluster defaults
openstack quota delete <project-id>
This removes all per-project quota overrides. The project reverts to the cluster-wide default quotas.

​
View Quota Usage

Show quota usage for a project
openstack quota show --usage <project-id>
The --usage flag adds In Use and Reserved columns alongside the quota limit, making it easy to identify projects approaching their limits.

​
Floating IP Pool Management

Floating IPs are allocated from the external network’s address pool. Monitor pool exhaustion at the cluster level:
List all floating IPs across all projects
openstack floating ip list --all-projects
Count floating IPs by status
openstack floating ip list --all-projects -f value -c Status | sort | uniq -c
If the external network’s address pool is exhausted, no new floating IPs can be allocated regardless of per-project quota limits. Coordinate with your network administrator to expand the provider network’s address range.
