thanks for posting this, I ran into two problems:

• apt doesn't like the unsigned keys for VirtualBox, need to wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add - before the apt update
• apt install libssl-dev in order to build the kernel?

This is great! Thanks for your contribution, Im getting the following error:

scripts/kconfig/conf --silentoldconfig Kconfig
CHK include/config/kernel.release

Makefile:551: recipe for target 'scripts' failed
make: *** [scripts] Error 2

any ideas?

Install libssl-dev

I ran the script but when I fired up the the vm it gets stuck in 'starting vm'. No relevant error message in the log file.

Everything correct, except this: sudo -E /sbin/rcvboxdrv setup

My out:
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

@voxsoftware Did you solve this error?

For me worked this bootscript x86_64 4.10.8 std #1
