Can't set quota for Fixed IPs and quota shows different values

[Alexander Koryagin]

Hello,
Please take a look at the to issues:
  1) Different components show different values for quota:
  2) It is not possible to set quota for "Fixed IPs".

My env:
MOS 9.0 ISO #217
3x controllers + 2x compute,cinder

Details:
(1) Different components show different values for quotas.

  In Horizon WEB set quota for 'Floating IPs' = 48 for 'admin' project.
  Identity -> Projects -> admin -> Modify Quotas -> Floating IPs = 48

  Check in console for controller:
  # openstack quota show admin | grep floating
      >> OK: floating-ips 48
  # nova quota-show --tenant admin | grep floating
      >> NOK: floating_ips -1
  # neutron quota-show admin | grep floating
      >> NOK: floatingip 50
  All three different numbers: 48, -1, 50

  The same for "Security Groups" = 7:
  # openstack quota show admin | grep secgroups
      >> OK: secgroups 7
  # nova quota-show --tenant admin | grep security_groups
      >> NOK: security_groups -1
  # neutron quota-show admin | grep security_group
      >> NOK: security_group 10
  All three different numbers: 7, -1, 10

(2) It is not possible to set quota for "Fixed IPs".

  There are no such value inside Horizon in 'Quota' tab for existing or during creation of new projects.
  Identity -> Projects -> %project name% -> Modify Quotas
  Identity -> Projects -> Create project -> Quotas
  (see attached 'quotas_create_new_prj.png')

  If I try to set this value in console it remains the same.
  As there are no output, all looks like value was sec successfully.
  But it wasn't and remains to be '-1'.

  # nova quota-update --fixed-ips 7 admin
  # nova quota-show --tenant admin | grep 'fixed_ips'
      >> NOK: fixed_ips -1

  # nova quota-class-update --fixed-ips 7 admin
  # nova quota-class-show admin | grep 'fixed_ips'
      >> NOK: fixed_ips -1

  # openstack quota set --fixed-ips 7 admin
  # openstack quota show admin | grep fixed-ips
      >> NOK: fixed_ips -1

  Inside 'neutron quota-show' there are no 'fixed-ips' quota:
  # neutron quota-show admin ## No fixed-ips

Here is content of my 'openrc' file:
root@node-4:~# cat openrc
    #!/bin/sh
    export OS_NO_CACHE='true'
    export OS_TENANT_NAME='admin'
    export OS_PROJECT_NAME='admin'
    export OS_USERNAME='admin'
    export OS_PASSWORD='admin'
    export OS_AUTH_URL='http://10.109.1.3:5000/v2.0'
    export OS_DEFAULT_DOMAIN='Default'
    export OS_AUTH_STRATEGY='keystone'
    export OS_REGION_NAME='RegionOne'
    export CINDER_ENDPOINT_TYPE='internalURL'
    export GLANCE_ENDPOINT_TYPE='internalURL'
    export KEYSTONE_ENDPOINT_TYPE='internalURL'
    export NOVA_ENDPOINT_TYPE='internalURL'
    export NEUTRON_ENDPOINT_TYPE='internalURL'
    export OS_ENDPOINT_TYPE='internalURL'
    export MURANO_REPO_URL='http://storage.apps.openstack.org/'

What is the quota driver used in Nova?(quota_driver option value in nova.conf)

[Roman Podoliaka (rpodolyaka)]

^ look like you use NoopQuota driver (which specifically returns -1 to denote the fact that quotas *are not* checked).

Not sure what openstackclient refers to.

Does neutron have a notion of fixed IPs at all? Isn't it ports?

[Eugene Nikanorov (enikanorov)]

No, it's a derived notion. The quota is for ports, fixed ips are limited implicitly by ports*subnets limit

Ok, it looks like we used default driver and it is expected behaviour.
We are going to check this with Nova Quotas Driver.
