I suspect you're looking for the linux-virtual metapackage, and dependencies thereof for your kernel. You may wish to look at the available Cloud Images [1], which are likely suitable for deployment in your target environment with little or no modification. If the selection of modules in linux-virtual is insuffient for your target environment, the other modules are also available in the dependencies of the linux-image-extra-virtual package. 1: http://cloud-images.ubuntu.com/ -- Emmet HIKORY -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss

I don't know the answer, but it looks like linux-virtual just depends on the regular kernel: $ apt-cache depends linux-virtual linux-virtual Depends: linux-image-virtual Depends: linux-headers-virtual $ apt-cache depends linux-image-virtual linux-headers-virtual linux-image-virtual Depends: linux-image-3.5.0-15-generic linux-headers-virtual Depends: linux-headers-generic -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
Specialized kernel/base system for VM's/VE's
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.: +49 (30) 3464615-20 Fax: +49 (30) 3464615-59 enrico.weig...@vnc.biz; www.vnc.de -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
Re: Specialized kernel/base system for VM's/VE's
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. 2012/9/24 Enrico Weigelt enrico.weig...@vnc.biz Hi folks, is anyone currently working on optimized/minimized kernel and base packages for VM's ?
