Hi All, if anybody is interested I have created a simple docker container for openstack which runs the stress tool (http://linux.die.net/man/1/stress) inside. It can be used to test for example CPU or memory limits. You can find the container in the official docker index: https://index.docker.io/u/dkuffner/docker-openstack-stress/ On the description you also find a example how to use it. regards, Daniel
