ALM-70203 Virtual Interfaces Fail to Be Brought Online

ALM-70203 Virtual Interfaces Fail to Be Brought Online


When a VM interface is brought online, networks fail to be configured, and this alarm is generated.


Alarm ID

Alarm Severity

Auto Clear







Fault Location Info

host_id: specifies the ID of the host for which the alarm is generated.

Additional Info

  • The first parameter lists virtual ports for which the alarm is generated.
  • The second parameter Virtual Interfaces Fail to Be Brought Online specifies that the virtual port fails to be brought online.

Impact on the System

Networks of the VM interface are disconnected.

Possible Causes

  • In the Region Type I scenarios, as RabbitMQ is faulty, the backend agent fails to obtain the port information through RPC. As a result, the port network configuration cannot be delivered.
  • In other scenarios, neutron-server is abnormal, for example, database entry update and deletion are performed simultaneously, third-party driver is abnormal, and the backend agent fails to query or update the port information.


  1. In the Region Type I scenario, check whether RabbitMQ is normal by performing operations provided in ALM-73401 Faulty RabbitMQ Service. If RabbitMQ is normal or recovers, go to 2. Otherwise, go to 7.
  2. Use PuTTY to log in to the first FusionSphere OpenStack node through the IP address of the External OM plane.

    The default user name is fsp. The default password is Huawei@CLOUD8.

    The system supports both password and public-private key pair for identity authentication. If the public-private key pair is used for login authentication, see detailed operations in Using PuTTY to Log In to a Node in Key Pair Authentication Mode.

    To obtain the IP address of the External OM plane, search for the required parameter on the Tool-generated IP Parameters sheet of the xxx_export_all.xlsm file exported from HUAWEI CLOUD Stack Deploy during software installation. The parameter names in different scenarios are as follows:
    • Region Type I scenario:

      Cascading system: Cascading-ExternalOM-Reverse-Proxy

      Cascaded system: Cascaded-ExternalOM-Reverse-Proxy

    • Region Type II and Region Type III scenarios: ExternalOM-Reverse-Proxy

  3. Run the following command and enter the password of user root to switch to user root:

    su - root

    The default password of user root is Huawei@CLOUD8!.

  4. Run the following command to disable user logout upon system timeout:


  5. Importing Environment Variables.
  6. Obtain the VM port UUID based on the alarm details and run the following command to update the port attribute to trigger port online processing. Wait until the alarm is cleared. If the alarm is cleared after five minutes, no further action is required. Otherwise, go to 7.

    neutron port-update {port_uuid} --admin-state-up False//Interrupt the network communication of the port.

    neutron port-update {port_uuid} --admin-state-up True//Restore the network communication of the port.

  7. Contact technical support for assistance.
