Sometimes in a fresh day you see things differently... I've added all users to group vboxsf. Not that I find the solution particularly elegant (I'd accept a better answer). But it works and I don't quite see harm on it. There were two users in the vm beside oracle, their ids are: davfs2and dm. No idea what's their use.

There is no automatic way to do this. This is not a question of intent but of nature: The creators of virtual machine managers do not merely want to hide the host's IP, the very nature of the host/guest relationship creates an impenetrable barrier between these two systems.

Programs that aren't doing anything will get swapped out. So you don't need to go for minimalistic on RAM usage. Do avoid background programs that aren't paused waiting for user input.

Have you looked at the MATE or XFCE desktop? they are both full featured DEs and will run significantly lighter than Unity, and are simple to setup in a basic Ubuntu installation. If you need to go lighter, ...
