Error mounting persistent volume on SELinux systems

In some cases, primarily when using a Linux distribution that uses SELinux to provide access control for Docker containers, when starting an Appliance Container and mounting a persistent volume, the container fails to start with Permission denied errors appearing in the Docker logs or as console output.

Use the z switch to the -v mount option to resolve it.

Example: SELinux Volume Error

[root@dc-a3100-3740 ~]# docker run -it --env=DS_MANAGER_EXTERNAL_CONNECT_IP=192.168.28.141 
--env=DS_MANAGER_EXTERNAL_CONNECT_PORT=8503 -p 8503:443 -p 8502:80 
-v /home/docker-persistence/docker-nat-mgr2:/container-persistence:rw 
--hostname=“docker-nat-mgr2” 1bb97d13f249
Usage of loopback devices is strongly discouraged for production use. 
Either use `--storage-opt dm.thinpooldev` or use `--storage-opt dm.no_warn_on_loop_devices=true` 
to suppress this warning.
