Wonderful (actually the introduction of host interface networking in 2.1.0 has been an amazing feature!). Now another user, ""user2"", wants to run his own VM. The problem is that with NAT networking the VM starts and works correctly, but if I select HOST networking it fails to start with the following error: Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_PERMISSION_DENIED). Unknown error creating VM (VERR_PERMISSION_DENIED).
