[Grml] OT: grml in remote VirtualBox

Hi,

Anyone has rdesktop to remote VirtualBox grml before?

I want to run grml in remote headless VirtualBox, but also want to have a local X env for other people who does not have local X, using rdesktop connecting to grml.

So far I haven't been able to:

$ rdesktop 192.168.2.103 & ERROR: 192.168.2.103: unable to connect

Has anyone done that before, or knows how?

Thanks
