Hello, I don't think you'll see a that lightweight kernel in distributions like Ubuntu. But saying that, you probably don't know how the Linux kernel work: most of the functions of the kernel (except core functions) can be compiled directly into the kernel or compiled as a module. Distributions like Ubuntu are mostly using module when available. With modules, when your computer need a function that is not in the kernel core it loads the related module into the memory. Conclusion: the only thing modules takes is disk space (try a du -sch /lib/modules to know how much) but not memory or other ressources until they are loaded. So, compiling a very lightweight kernel (much more that the Ubuntu one) is possible. You can do it following tuto on the net. But it doesn't make sense on a VM. It only makes sense on embeded hardware where each megabytes is good to save.<div class="yj6qo ajU"><div id=":7g" class="ajR" tabindex="0"><img class="ajT" src="https://mail.google.com/mail/u/0/images/cleardot.gif"></div></div> <div class="gmail_quote"> 2012/9/24 Enrico Weigelt <<a href="mailto:enrico.weigelt@vnc.biz" target="_blank">enrico.weigelt@vnc.biz</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi folks, is anyone currently working on optimized/minimized kernel and base packages for VM's ? My goal is having a really minimized base system for VMs and VEs, which don't have anything that's really needed there (eg. VEs dont need all the kernel related stuff, VMs just only those parts which are really required for running in an virtio-based environment, etc, etc). cu -- Mit freundlichen Grüßen / Kind regards Enrico Weigelt VNC - Virtual Network Consult GmbH Head Of Development Pariser Platz 4a, D-10117 Berlin Tel.: <a href="tel:%2B49%20%2830%29%203464615-20" value="+4930346461520">+49 (30) 3464615-20</a> Fax: <a href="tel:%2B49%20%2830%29%203464615-59" value="+4930346461559">+49 (30) 3464615-59</a> <a href="mailto:enrico.weigelt@vnc.biz">enrico.weigelt@vnc.biz</a>; <a href="http://www.vnc.de" target="_blank">www.vnc.de</a> -- Ubuntu-devel-discuss mailing list <a href="mailto:Ubuntu-devel-discuss@lists.ubuntu.com">Ubuntu-devel-discuss@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss</a> </blockquote></div> -- Nicolas MICHEL
