I added the parameter, restarted. I then purged VBox, installed again (it deleted and compiled the module). I created a VM (windows XP), but when I try to start it, it says: Unknown error initializing kernel driver (VERR_VM_DRIVER_VERSION_MISMATCH). VBox status code: -1912 (VERR_VM_DRIVER_VERSION_MISMATCH). Código de Resultado: 0x80004005 Componente: Console Interface: IConsole {1dea5c4b-0753-4193-b909-22330f64ec45} I read some thread saying that it's cause by an old kernel module version (My installation is brand new). I still did execute ""modprobe -r vboxdrv && modprobe vboxdrv"", as they said. No better luck after that. " defect closed other VirtualBox 1.4.0 worksforme other other
