I've done the update to VirtualBox 3.1 yesterday (on an openSuSE 11.1). Since that, the port forwarding configuration on the guest linux I used didn't work anymore.
The symptoms are that a netstat on the host "says" that there is nothing listening on the port 2222. I have already re-configure the guest with VBoxManage (GuestPort - HostPort - Protocol), but it didn't change anything... :/
Anybody can help me please ?
Thanks very much!!!
