We can set the container cpuset.cpus diring the creation and it will not need to call to update resources after the container creation. Additional side effect of the change, that the runc process that responsible to create the container will run with the same CPU affinity because the runc runs on the cpuset provided in the config.json arg. It will allow to prevent undesirable interupts on isolated CPUs. Signed-off-by: Artyom Lukianov <alukiano@redhat.com>
