Description
The Guest-System (Win7 32bit) does not start. The Host-System (OpenSuse Tumbleweed 64bit with VirtualBox 6.1.13) uses an Intel B960 Laptop-CPU without VT-X support. Usually Virtualbox uses NEM as a fallback which seems not to work anymore, I get a "VT-x is not available (VERR_VMX_NO_VMX)."-Message instead. Here are the logs:

The VM Settings are as follows: System-Processor: 1 without any extended features System-Acceleration: Paravirtualization Interface: None, Hardware-Acceleration: None
Raw mode was dropped starting with 6.1, VBox requires a CPU with hardware assisted virtualization support now. The NEM mode is something entirely different and only used as a fallback on Windows if Hyper-V is enabled.
