where:

<SDL_DIR> - directory where SDL is installed. The directory is specified during Hosting Director installation. By default, it is /opt/hostdir.

  6. Run Parallels Sphera services management tool and configure QoS to be loaded:

    # sphadmin

    Choose the following option: "Enable QoS in the next boot"
  7. Reboot the server:

    # shutdown -r now

  8. Check the booted kernel's version:

    # uname -r

    Check if the sphera_control2 module is loaded:
