Failed to Load VirtualBox image - VT-x features locked or unavailable in MSR


Failed to Load VirtualBox image.

While loading the virtual box existing image after the importing, I got the following error.

Failed to open a session for the virtual machine XP.

VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}

To solve the issues, I opened the image settings and did the following changes.

This changing your bios settings of your virtual machine for the first load.

  2. This just masks the underlying problem. Disabling VT-x will significantly lower the performance of your VMs.

    1. If we are importing the VBox image from exported from another machine and starting, I used to get this error. And I found we need to enable the virtualization settings in BIOS settings if the processor supports, since many of the intel core processor does not support the in built virtualization. By default virtualization is disabled for processors and we can enable it. In this case we dont want to disable the enable VT-x feature under System/Acceleration. But if our processor does not support the virtualization, I saw many times we need to disable this feature for starting the VBox image. Still I am finding more convenient reason and solution for this problem since it occurs frequently while working with exported VBox image.
