I guess you want to connect to a VirtualBox guest running on another machine and running with the VRDE extension enabled. This extension enables connections to the guest console through the VRDP protocol (VirtualBox Remote Display Protocol). So you need a VRDP client.
VRDP is essentially the VirtualBox implementation of Microsoft RDP, the Remote Desktop Protocol. So an RDP client should work to connect to a VirtualBox guest having it's VRDP port enabled.
In the UNIX world, one such client is rdesktop. It is available in the usual Linux distros, for OSX and the other *BSD variants. Another alternative, if you're using KDE, is krdc
, the KDE RDP client. Check your package manager.
On Microsoft systems, you should be able to use the Microsoft Terminal Services Connector or mstsc.exe
All those RDP client take one mandatory parameter: the host to connect to (as an IP or as a hostname) and one optional parameter: the port to connect to on the guest host (usually defaulting to 3389).
If it's not what you're looking for, could you make your question clearer please?
What kind of operation do you want to perform on VirtualBox? Is it to do something inside the guest OS (like ssh would do) or to manipulate the guest (pause it, attach a drive, shut it down)? And from which platform (OS) are you trying to connect to the guest? – Tonin – 2012-12-21T20:22:18.487
I want to connect as if in front of the physical machine, since the start. like
xen start DOMAIN_NAME -c
orxen console DOMAIN_NAME
. understand if you've used Xen – rkmax – 2012-12-21T21:27:40.390Are you trying to connect from the VirtualBox host or from another independent host? What OS are you running on that host? – Tonin – 2012-12-21T21:38:50.753
