Hi, In "host interface networking" mode VirtualBox actually creates a bridge to the network attached to the selected host interface. Since the network is not available the interface is not functioning, hence no communication. If you need to be able to access the host (and possibly other hosts if the host does routing) but you cannot rely on the fact that some physical interface is always attached, you can create TAP device with VBoxTunctl and attach to it.
