How to connect two VirtualBOX's like this:

Vitrual 0 (eth0) <-----cable------> (eth0) Virtual 1

A virtual cable?

Seriously, all you need to do is put them in the same network. Have you tried connecting them both to the internal network?

VirtualBox is the name of the application program. It is not the name of the virtual machines. Call them vms or guests.

but.... at the same internal network

guest 0 (10.0.0.1) [eth0] <-------cable--------> [eth0] (10.0.0.2) guest 1

quest 2 (10.0.0.2) [eth0]

from guest 2 i can ping 0 and 1 :/ i don't like this

If you don't like that, put guest 2 in a different internal network!

so, quest don't have that feature right now?

You may find it useful to actually read the user manual, chapter 6. Take particular notice of named internal networks.
