Changes

From the host system, all containers processes are visible, and all the container files are accessible (under <code>/vz/root/$CTID</code>).Host system administrator can set containers' parameters, access all containers files, send signals to containers processes etc.  Containers mass-management is easy with some shell scripting and commands like <code>exec</code> and <code>enter</code>. For example, to add a user jack to all running containers the following command can be used:  for CT in $(vzlist -H -o ctid); do vzctl set $CT --userpasswd jack:secret; done
