Error on VirtualBox: VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED)
I recently got a Oracle VM Virtualbox appliance. After I imported it I got the following error when I tried to start it.
Failed to open a session for the virtual machine Fusion Middleware.
VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED).
|Result Code:||E_FAIL (0x80004005)|
I did some googling and the suggested solution was to uncheck the Enable VT-x/AMD-V Hardware Virtualization settings (found in Settings> System>Acceleration). But since my virtual machine was 64-bits hardware virtualization is required. So if I disabled the Enable VT-x/AMD the virutal machine would not boot.
My problem was that virtualization settings on my pc were disabled. I have a Dell T5500. So I followed the following steps to activate my hardware virtualization settings:
- Reboot the pc. Press F12 when the boot process starts
- Select change settings
- Select Virtualization Support> Virtualization check the Enable Intel(R) Virtualization Technology
- Select Virtualization Support > VT for Direct I/O check Enable Intel(R) VT for Direct I/O
Now the virtual machine boot without any problem.
