ERROR VBox 3.2.8 and VT-x/AMD-V Hardware Acceleration
Posted: 8. Oct 2010, 16:02
Hi Folks,
I have VirtualBox 3.2.8 r64453 installed on Ubuntu 9.10, my system is based on the M3A78-CM motherboard. When I try to start a VM I get the error message below.
Virtual Box Error Message
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.
Please ensure the you have enabled VT-x/AMD-V properly in the BIOS of your host computer.
Now after searching online and trying every single suggestion I can find I am still unable to resolve this problem and Im at my whits end. I have tried the following to get this error to SPAM_SEARCH off.
- Updated BIOS to latest version
- Confirmed that the virtualization setting was enabled in the BIOS (cold booting / powering off each time)
- Disabled and re-enabled virtualisation settings in BIOS
All of the posts I have found seem to refer to older versions of VirtualBox that had this issue however I can find nothing similar related to the most recent version (bar people not having virtualisation turned on in their BIOS). But with the posts I have found it seems that it worked with a version of VBox that didnt check for for virtualisation being enabled at all. Also if I look in my log files I see the following error:
HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_SVM_IN_USE
HWACCM: VMX MSR_IA32_FEATURE_CONTROL=0
Any help would be greatly appreciated.
