You can delete a container environment with OpenVZ by following these steps:
1. First, you need to stop the container if it is running. Use the command:
```
vzctl stop [ContainerID]
```
Replace `[ContainerID]` with the ID of the container you want to stop.
1. Once the container is stopped, you can delete it using the following command:
```
vzctl destroy [ContainerID]
```
Again, replace `[ContainerID]` with the ID of the container you want to delete.
Remember to only delete containers that you are certain you no longer need, as this process is irreversible. Make sure you backup any important data from the container before deleting it.
