I think I had the CONFIG flags set to Y already. The BIOS change and a shut down before booting was what apparently solved it. I shutdown the laptop and went to bed, the next morning after booting the machine I fired up vbox and all worked. I have now a fully functional Windows7 virtual machine; it is impressive how fast it boots and shuts down as virtual machine; also everything seems to work robustly. I installed goggle scketch up under Win7 and it works nicely. Thanks for the inputs. -- Valmor

Rebooting fixes the problem temporarily. If you notice that behavior you may want to go ahead with any BIOS upgrade to see if that fixes it. kashani

None of the selections below that are selected in my kernels. They run 64-bit VMs fine, but I don't have VBox 3. Your host kernel should NOT have CONFIG_PARAVIRT_GUEST but your guest kernels should. That's the consensus my machines have yielded, both AMD/Intel and 32/64 bits, but there are probably other options.
