Enable memory oversubscription on the compute controller

This section covers the procedure to enable the memory oversubscription service on the compute controller.

Note:
  • By default, the memory oversubscription service daemon is not enabled.

  • If you are using a hardware stack with multiple compute controllers, you need to enable the memory oversubscription service on each compute node.

To enable memory oversubscription, follow these steps:

  1. Execute the following command to start the memory oversubscription service:

    sudo systemctl start tacp-memory-oversubscription.service

  2. Execute the following command to ensure the service is up and running:

    sudo systemctl status tacp-memory-oversubscription.service

    Figure 1. Verifying the memory oversubscription service is running

  3. Execute the following command to set the service to start on reboot:

    sudo systemctl enable tacp-memory-oversubscription.service
