You can stop a specific container in OpenVZ by using the `vzctl` command. Follow the steps below:
1. Open a terminal window.
1. Get a list of all running containers by typing the following command:
```
vzlist -a
```
This will list all the available containers with their respective CTID (Container ID)
1. Find the CTID of the container you want to stop.
1. Type the following command to stop the container:
```
vzctl stop CTID
```
Replace “CTID” with the actual ID of the container you want to stop. This command will stop the container and all processes within it.
Remember you need root privileges to execute `vzctl` commands. If you are not logged in as root, you would need to use `sudo` before the commands.
