VirtualBox: Problem with hardware acceleration.
I have been using Virtualbox for about a year without problems. But a few weeks ago it started giving an error when ever I try to start a guest OS. It says:
"VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot."
I am running the amd64 version of debian and the guest is the win XP 64 bit.
I have tried googling the error and found a fix. By doing a cold shutdown i.e. turning the computer off unplugging it and letting the capacitors drain, then starting it up again. That fix only works for people that have suspended their computers, since I guess it doesn't set things correctly after it starts up again. But I tried it anyways and it didn't work. I have also tried turning the hardware accelerated virtualization off just to see what would happen and the error doesn't change. It still says it is enable but not operational. I have also reinstalling Virtualbox but that didn't help either. Does anyone have any ideas on how to fix this?
