7248	AMD-V enabled but not operational	ldp		"I have an AMD Phenom X4 9850 and an M3N-HT Deluxe mainboard.
For the past 7 months everything worked perfectly, but I rebooted yesterday and when I tried starting any of my virtual machines, got this error:

""VT-x/AMD-V hardware acceleration is enabled but not operational. Please ensure that you have enabled it in the BIOS of your host computer.""

I've redone the settings, power cycled, reseated the RAM, restored BIOS settings to factory defaults, but nothing works."	defect	closed	VMM/HWACCM	VirtualBox 3.2.6	worksforme			other	other
