Hi Amos, thanks! I've been thinking about those scripts, let me summarize my thoughts: * If we are going to make this using scripts, then we should try as much as possible to be distro agnostic. * We could detect services present on guest first before trying to disable them, ie, instead of just issuing a service koan stop, verify if there's a /etc/init.d/koan first. * Have you considered doing this env setup using shell commands typed on an ssh session, such as session = vm.wait_for_login() session.cmd('service auditd stop') Rather than a script? It's one less script to maintain under the scripts/ directory. * Your approach is a blacklist of services that will be turned off. What if we used a 'whitelist' approach and kept a list of the fundamental services needed and turn off *everything else*? Please let me know what you think about this. I'm not applying this for now. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
