            Bug ID: 1046469
           Summary: docker privileged mode with cmd /sbin/init - agetty &
                    high cpu
           Product: Fedora
           Version: 20
         Component: docker-io

Description of problem:
docker containers in privileged mode mess with the host agetty and produce very
hicht cpu load

Version-Release number of selected component (if applicable):
Fedora 20
Docker 0.7.1, 0.7.2

How reproducible:
docker run -privileged -d mattdm/fedora:latest /sbin/init

Actual results:
docker container runs
cpu load is very high - agetty
stopping the container & the docker daemon do not free the cpu resources
one have to kill the agetty process

Expected results:
docker container runs

Additional info:
In my real case i run rhel containers with puppet & ssh daemons for a small
puppet lab.

The reason i met this bug is that running docker container with /sbin/init cmd
under RHEL 6.5 require priviliged mode.
