The only issue is floating_ips don't change in the GUI i.e. dashboard.

Depending on which quotas you want to modify you will either use Nova or Neutron's API. Neutron is used for the networking related quotas (routers, networks, subnets, etc) and Nova is used for the compute resources (RAM, CPU, etc).

To set quotas using the Nova API you will use a PUT against '/v2.1/os-quota-sets/​{tenant_id}​' with the following as an example:

"quota_set": {
    "cores": 20,
    "fixed_ips": -1,
    "floating_ips": 10,
    "injected_file_content_bytes": 10240,
    "injected_file_path_bytes": 255,
    "injected_files": 5,
    "instances": 10,
    "key_pairs": 100,
    "metadata_items": 128,
    "ram": 51200,
    "security_group_rules": 20,
    "security_groups": 45,
    "server_groups": 10,
    "server_group_members": 10

You could also use the CLI's to do this and use '--debug' to extract the exact API call being used.

Sure, first issue 'nova quota-show --tenant <tenant-uuid>' to see the quota classes and then to actually update them you would do:

nova quota-update --tenant <tenant-UUID> --instances <new_quota>

The example above would update the instances quota on the specified project (tenant).

Doesn't work with OpenStack Kilo, maybe these were from Juno release. Only this command works nova quota-show --tenant <tenant-uuid>

I was referencing the current CLI reference documentation. There may be an underlying issue, did the CLI return a 500 error as well?

Returns unknown command --tenant
