    **Virtual machine configuration**
    To configure a virtual machine to boot creat a link to the `pxeboot.0` with the name you used (e.g. `$MyVM`)

    MyVM=testvm
    cd ~/.config/VirtualBox/TFTP/ # cd ~/Library/VirtualBox/TFTP/
    ln -s pxelinux.0 ${MyVM}.pxe
    If needed, reconfigure your VM for network boot using NAT:

    vboxmanage modifyvm ${MyVM} --nic1 NAT --nictype1 virtio
    vboxmanage modifyvm ${MyVM} --boot1 net --boot2 disk --boot3 none --boot4 none
    * Now you should be able to boot the VM (and at least show the SysLinux menu and eventually continu with your `APPEND` line ..)
