Container Virtualization

Which statement about the lxc-checkpoint command is correct?

  • A It creates a clone of a container.
  • B It doubles the memory consumption of the container.
  • C It only works on stopped containers.
  • D It writes the status of the container to a file.
  • E It creates a container image based on an existing container.
Explanation

lxc-checkpoint saves a container checkpoint—its runtime state and associated checkpoint metadata—to disk for later restoration. The --stop option can optionally stop the container after the checkpoint is written, so a stopped container is not a prerequisite.
