I'd like to run windows xp on RDP:

$ VBoxManage modifyvm winxp32 --vrdeport 3389
$ VBoxHeadless -s winxp32 -v on
Oracle VM VirtualBox Headless Interface 4.1.18_Debian
(C) 2008-2012 Oracle Corporation
All rights reserved.
(waiting)

in another window:

$ telnet localhost 3389
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

Yes, I've read about extension:

$ sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.1.20-80170.vbox-extpack
0%...
Progress state: NS_ERROR_FAILURE
VBoxManage: error: Failed to install "Oracle_VM_VirtualBox_Extension_Pack-4.1.20-    80170.vbox-extpack": Extension pack 'Oracle VM VirtualBox Extension Pack' is already     installed. In case of a reinstallation, please uninstall it first

Looked through all manuals and all help requests. No success. What's wrong? Any ideas?

The problem was caused by the fact that vbox and addition had different versions. You cans see it in the console output.
