Instead of pausing the sanbox, this patch just pauses the container allowing the communication with the agent. The communication with the agent should be still possible even if all containers are paused, because of we don't know when a new container can be created in the same sandbox. Depends-on: github.com/kata-containers/agent#246 fixes #317 Signed-off-by: Julio Montes <julio.montes@intel.com>
