Yes, this is normal, when you exec 'nova restart container-id', nova-docker will do some other things --- setup the network information as well as VM. And you can see the source code at https://github.com/stackforge/nova-docker/blob/master/novadocker/virt/docker/driver.py in the function reboot about the lines 572.
