As an administrative user, you can view and update project quotas. List the default Compute service project quotas: $ nova quota-defaults +-----------------------------+-------+ | Property | Value | +-----------------------------+-------+ | metadata_items | 128 | | injected_file_content_bytes | 10240 | | ram | 51200 | | floating_ips | 10 | | key_pairs | 100 | | instances | 10 | | security_group_rules | 20 | | injected_files | 5 | | cores | 20 | | fixed_ips | -1 | | injected_file_path_bytes | 255 | | security_groups | 10 | +-----------------------------+-------+ To update a default value for a new project, update the default property in the /etc/nova/nova.conf file, as follows: $ nova quota-class-update default --key value For example: $ nova quota-class-update default --instances 15 Verify your changes by showing the quotas for the quota class, as follows: $ nova quota-class-show default +-----------------------------+-------+ | Property | Value | +-----------------------------+-------+ | metadata_items | 128 | | injected_file_content_bytes | 10240 | | ram | 51200 | | floating_ips | 10 | | key_pairs | 100 | | instances | 15 | | security_group_rules | 20 | | injected_files | 5 | | cores | 20 | | fixed_ips | -1 | | injected_file_path_bytes | 255 | | security_groups | 10 | +-----------------------------+-------+

Place the tenant ID in a usable variable, as follows: $ tenant=$(keystone tenant-list | awk '/tenantName/ {print $2}') List the currently set quota values for a tenant, as follows: $ nova quota-show --tenant $tenant For example: $ nova quota-show --tenant $tenant +-----------------------------+-------+ | Property | Value | +-----------------------------+-------+ | metadata_items | 128 | | injected_file_content_bytes | 10240 | | ram | 51200 | | floating_ips | 12 | | key_pairs | 100 | | instances | 10 | | security_group_rules | 20 | | injected_files | 5 | | cores | 20 | | fixed_ips | -1 | | injected_file_path_bytes | 255 | | security_groups | 10 | +-----------------------------+-------+

Get the tenant ID, as follows: $ tenant=$(keystone tenant-list | awk '/tenantName/ {print $2}') Update a specified quota value, as follows: $ nova quota-update --quotaName quotaValue tenantID For example: $ nova quota-update --floating-ips 20 $tenant $ nova quota-show --tenant $tenant +-----------------------------+-------+ | Property | Value | +-----------------------------+-------+ | metadata_items | 128 | | injected_file_content_bytes | 10240 | | ram | 51200 | | floating_ips | 20 | | key_pairs | 100 | | instances | 10 | | security_group_rules | 20 | | injected_files | 5 | | cores | 20 | | fixed_ips | -1 | | injected_file_path_bytes | 255 | | security_groups | 10 | +-----------------------------+-------+ To view a list of options for the quota-update command, run: $ nova help quota-update
