Firstly thanks for creating virtualbox.
I have been playing with it over the last 6 months on windows & headless linux hosts with pretty much every guest OS you can name
I currently have an issue running VBoxHeadless under vista.
If I setup and run a debian guest using the normal VBox software using Nat, networking works fine.
If I then run the guest using VBoxHeadless I loose network.
Version 2.0.4
Host Vista 32bit
Guest Debian 2.6.26
I've setup Nat under the VBox windows GUI.
I've tried running : VBoxManage modifyvm "Debian" -nic1 nat
Am I missing something?
