AMD-V not working — at Initial Version

Reported by: palomino Owned by:
Component: VMM/HWACCM Version: VirtualBox 3.1.0
Keywords: AMD-V Cc:
Guest type: Windows Host type: Linux


Cpu: AMD AthlonIIx3 425. Motherboard: GA-MA78GM-US2H HostOS: Ubuntu 9.10 GuestOS: Windows 2003 (2 processors allocated) Virtualization is enabled in BIOS.

When i upgraded to 3.1.0, it reported "VT-x is not available. (VERR_VMX_NO_VMX)." when i tried to start the guest os. 3.0.12 worked fine. Reinstall 3.1.0 can not fix the issue. Remove 3.1.0 -> install 3.0.12 -> remove 3.0.12 -> install 3.1.0 works. But if I restart the computer, I have to do that again. BTW: It did not happen on another computer with intel's cpu.
