Optimization Process

A Linux ECS can run properly only when native KVM (VirtIO) drivers have been installed on it and disk identifiers in its GRUB file and fstab file have been changed to UUID.

Preparations

  1. Use the Linux image to be optimized to create an ECS, and start and log in to the ECS.

  2. Check whether the private image needs to be optimized.

    For details, see Checking Whether a Private Image Needs to be Optimized.

Process

  1. Change disk identifiers in the GRUB file to UUID.

    For details, see Changing Disk Identifiers in the GRUB File to UUID.

  2. Change disk identifiers in the fstab file to UUID.

    For details, see Changing Disk Identifiers in the fstab File to UUID.

  3. Install native KVM drivers.

    For details, see Installing Native KVM Drivers.

  4. Delete log files and historical records, and stop the ECS.

    For details, see Clearing System Logs.

  5. Create a Linux private image from the ECS.
