No. The problem is that the kvm modules change the operating mode of the host CPU (the so-called root mode), even if the modules are only loaded but not really used. VirtualBox cannot work in that mode. To use the root mode, this mode has to be initialized by VirtualBox itself, not by any other instance. Kind regards, Frank -- Dr.-Ing.
