An openvz container can be stopped with

vzctl stop <id>

, but this needs the cooperation from the init inside the container. In case a container is compromised a way is needed to stop the container withouts its cooperation. Something like a

vzctl kill <id>

is needed which kills all processes inside the container and puts it into the stopped state. Such a kill command is not listed in the manpage.

How can an openvz container be killed/stopped without needing it's cooperation?
