Enable or disable memory oversubscription within application instances

You enable or disable the memory oversubscription within application instances as described below.

For Linux application instances, no action is needed. Memory oversubscription is supported automatically once enabled on the compute controller.

For Windows application instances, follow these steps to enable/disable the memory oversubscription service:

Note

  • Templates provided by Lenovo Cloud Marketplace already include the necessary drivers. You need to install them manually only if you are preparing your own custom template.

  • The Windows Memory Ballooning service is NOT installed by default in templates provided by Lenovo Cloud Marketplace. You need to install it manually for both ThinkAgile CP and your custom templates.

  1. Open the Windows PowerShell application with administrator privileges.
  2. To ensure that VirtIO drivers are installed, execute the following command:

    driverquery



    If the drivers are not present, install them manually as described in Install VirtIO drivers.

  3. Ensure that the memory ballooning service is listed and its status is Running by executing the following command:

    Get-Service



    If the memory ballooning service is not listed, install it manually as described in Install the Windows Memory Oversubscription service.

    If the service is not running, start it.

The memory oversubscription service is now enabled.
