Remote Access to VirtualBox: Can't Connect via Remote Desktop

Question

I have a host (Windows 7) and a VirtualBox on it (guest OS is Ubuntu), that uses the NAT adapter.
Also my host is in the local network (DHCP).

I have already set the ssh connection to the VB and also I have an Internet access from the guest OS.

Now I want to establish a remote connection to the Hudson which is running on Tomcat 6 which, in turn, is running on Ubuntu.
I have tried this:

1. VB -> Settings -> Display -> Remote Display -> checked enable server on 3389 port.
2. On my collegue's computer (Windows 7) opened Start -> Program -> Accessories -> Remote Desktop Connection.
   So that I use the NAT adapter my host and guest have the same ip.
   I have tried to connect to myIpAddress:3389, but it can't do this (not with the global id, nor with the local) [However It managed to connect to the host with the local ip].

Well, the other variant was to use the Bridge adapter.
But When I try to start the VM there is an error:

Unknown configuration node 
"//ssh" found in the configuration of IntNet instance #0 (VER_CGGM_CONFIG_UNKNOWN_NODE)

Did anybody face this problem?

Answer 1

My guess is the the remote display port is conflicting with your host Win7 remote desktop service or the windows firewall. I would suggest double checking the firewall settings and switching the remote display port in VirtualBox to something like 3390 (or some other unused port). I would consider it a "best practice" to change the Remote Display port to something other than 3389 with a Windows host.

As for the error with the bridged adapter, It would appear that you still have a port forward from the NAT configuration sticking around that is having trouble going away. Switch the adapter configuration back to NAT and clear out any settings that are present - trying adding a new rule, then saving and then removing it if none are showed to ensure the XML config file is updated.
