How to: Virtualbox configure Turnkey loopback network and shared folder permissions?

Hello,

Can someone help me? I wiuld like to:

- Configure virtial machine to share p2p network with host, some sort of "localhost" in virtual box, so web server is visible from host OS only.

- Tutorial for confifurig www in shared virtual machine folder is wrong on this site, permissions are problem.

Can someone edit it or give short tutorial how to move www (web server folder) so it can be accessed from host machine.

Thank you in advance people.

Best regards,
