How do I get VirtualBox to run with more than one CPU core on my Dell Desktop PC

Reported by: GusFernandez Owned by:
Component: host support Version: VirtualBox 3.2.12
Keywords: VT-X Cc:
Guest type: Linux Host type: Windows


I'm trying to use Sun VirtualBox on my Dell Optiplex 755 Desktop PC running Windows XP SP3 on an Intel Core 2 Duo E8400 3.00GHz processor and the latest version of VirtualBox (3.2.12) to run a Linux Kubunto Guest OS. This works very well as long as I only use only one of the two processor cores. If I try to enable the second core, I must also enable VT-X virtualization. However, in this case I always get an error Unknown error creating VM (VERR_VMX_MSR_LOCKED_OR_DISABLED) Result Code E_FAIL (0x0004005) Comonent: Console Interface: IConsole {6375231a-c17c-464b-92cb-ae9e128d71c3} I checked the system BIOS and virtualization as well as all other processor features are enabled, and there are no supervisor password locks. I successfully updated the BIOS from version A11 to the latest version A17 using a tool that I downloaded from the DELL website specifically for the Optiplex 755, but this did not help. I checked other websites regarding the VERR_VMX_MSR_LOCKED_OR_DISABLED message and I only get vague mentions of BIOS bugs on Dell computers. The same procedure works well on my Lenovo Laptop. I'm sending this same support request to DELL as well.
