# Boot up the virtual machine:
# - Enable KVM full virtualization support.
# - Intel Core 2 Duo processor.
# - Simulate an SMP system with 2 CPUs and 2 cores (needed for first boot!).
# - Set virtual RAM size to 3072 megabytes (3 GB).
# - Standard PC (Q35 + ICH9, 2009).
# - USB keyboard and mouse.
# - Apple SMC with OSKs (see above!).
# - With bootloader Chameleon or Chimera (see above!).
# - Define Base Board Information.
# - Standard VGA card with Bochs VBE (VESA 2.0) extensions.
# - With or without network.
# - Windowed or VNC mode.
# - Redirect the "monitor" to standart input/output.
# - Use the RAW image as S-ATA harddisk.
#   Alternative IDE support:
#     -device ide-drive,bus=ide.0,drive=Macintosh_HD
#     -drive id=Macintosh_HD,if=none,format=raw,file="${SOURCE}"
#
# - for OS X >10.9 needed:
#   $ sudo su - -c "echo 1 > /sys/module/kvm/parameters/ignore_msrs"
#
# - for macOS >10.12 needed:
#   Penryn instead of "-cpu core2duo" and "-machine pc-q35-2.4" (no_floppy=1)
