I am running an ubuntu server 16.04 LTS with virtualbox 5.2 and phpvirtualbox 5.2. All the necessary ports are open. I see the machine on my router - meaning machine is running. Neither the console nor my RDP client can access the machine. On top: the preview window turns black shortly after boot-up. I can see the first screen of my guest OS booting, then it suddenly turns black.
