A simple getopt-based argument parser is added for the /usr/sbin/bhyveload command, loosely based on its argument parser. The boot disk is guessed by iterating over all disks and matching their sources. If any non-default arguments are found, def->os.bootloaderArgs is set accordingly, and the bootloader is treated as a custom bootloader. Custom bootloader are supported by setting the def->os.bootloader and def->os.bootloaderArgs accordingly grub-bhyve is also treated as a custom bootloader. Since we don't get the device map in the native format anyways, we can't reconstruct the complete boot order. While it is possible to check what type the grub boot disk is by checking if the --root argument is "cd" or "hd0,msdos1", and then just use the first disk found, implementing the grub-bhyve argument parser as-is in the grub-bhyve source would mean adding a dependency to argp or duplicating lots of the code of argp. Therefore it's not really worth implementing that now. Signed-off-by: Fabian Freyer <fabian.freyer@physik.tu-berlin.de>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
