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

# step 4: build the virtual machine image
build-{ve,vm}: handle THE_* and DOT_BASE too Classic VEs don't carry any kernel since these are running under a single OpenVZ (or potentially LXC) kernel image; ARM Multiboot (TWRP in this particular case) allows to boot off a chroot via kexec, and we need a kernel in it for that, obviously. No bootloader required inside such VE though.

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.
