yes, you can also use virtualbox "snapshot" states (save snapshot, test, revert) which makes things easier and no need to reboot your own computer, I have also set an ssh so i can always ssh to the vbox machine too
there's a conf file for entrance in /etc which I assume you already seen, it should be used for autologin, so then you can enable / disable it from there
and so, bugs should be reported to their github project
