Raw Normal View History

initial build-vm feature Yes, mkimage-profiles is now able to build VM disk images. So far the support is pretty basic: - a single hard drive image with a single partition/FS - only stock root password is configurable - LILO is hardwired as a bootloader The resulting images tend to boot under qemu/kvm though. Please see doc/vm.txt for the warning regarding additional privileges and setup required. This was started back in February but I still hoped to avoid sudo/privileged helper (and libguestfs is almost as undistributable as can be)... Thanks: - http://blog.quinthar.com/2008/07/building-1gb-bootable-qemu-image-using.html - Alexey Morarash who reworked that as https://github.com/tuxofil/linsygen - led@, legion@, vitty@, aen@ for providing advice and inspiration

initial specific VM formats support Raw disk images are convenient and universal but there are custom formats like Qemu's qcow2 providing additional features, e.g. copy-on-write or space savings. All of this ultimately belongs to mkimage but in the mean time has been implemented here as well.

initial vm-{net,ssh} features A virtual machine isn't very useful if there are no means to access it; let's bring up the basic networking and provide root SSH access via pre-existing public key. As the remote access with known default credentials is roughly equivalent to just lending one's VMs to anyone with network access to it, the fallback root password is now exterminated; you have to provide one (or a long enough random string if you plan to use keys only, see e.g. apg utility).

proxy CLEANUP_PACKAGES down mkimage implementation requires that the variables to be passed to the scripts are to be prefixed with GLOBAL_ or INFO_ tags as appropriate; in this case the upstream makefile didn't care to.
