If it's similar to SSH in Windows 10 (developer feature) it behaves quite strangely with user account privileges. I tried to `vagrant up` a project configured to use VirtualBox but it was not successful and caused a whole load of file system permission errors in thr project directory mixed between SYSTEM and Andrew (my user account). Additionally, VirtualBox had trouble deleting the VM until a reboot.

This is the Vagrantfile: https://github.com/andrewmackrodt/boot2lxd/blob/develop/Vagr... - it creates and attaches an extra virtualdisk in the project directory which was owned by SYSTEM IIRC.

TL;DR the VM which should have worked did not work, my FS had weird permissions and a reboot was required to clean up VirtualBox.
