Fixing “Not in a hypervisor partition” error in VirtualBox

When trying to start a virtual machine(VM) using VirtualBox, we may receive the following error message: “Not in a hypervisor partition (HVP=0) (VERR_NEM_NOT_AVAILABLE)”. This often means the BIOS settings have virtualization turned off. To use VMs, we need to enable it. It makes possible for the computer to distribute resources more effectively.

Error Causes

1. VT-x is disabled (VERR_VMX_MSR_ALL_VMX_DISABLED):

Intel VT-x is a technology that helps virtual machines run better by letting them access the CPU directly. If VT-x is turned off in the computer’s BIOS, VirtualBox won’t be able to start the virtual machine.

2. AMD-V is disabled (VERR_SVM_DISABLED):

AMD-V is AMD’s version of virtualization technology. We need to enable it in the BIOS for VirtualBox to work properly. If AMD-V is disabled, VirtualBox won’t be able to use the CPU’s virtualization features, causing an error.

Error Fixes

To fix the “Not in a hypervisor partition” error, we need to enable virtualization in the computer’s BIOS or UEFI settings. Here’s are the steps to do so:

1. Initially, reboot the computer and enter the BIOS/UEFI settings. We can do this by pressing a specific key during startup (such as F2, F10, Delete, or Esc).

2. Go to the Configuration or Advanced tab.

3. Look for settings named Intel VT-x, AMD-V, IVT, or SVM.

4. Enable the virtualization feature by selecting it and pressing Enter.

5. If using an AMD processor, we may also need to enable Secure Virtual Machine mode.

6. Press F10 to save the changes and exit the BIOS settings.

7. Lastly, restart the computer and launch VirtualBox again. The virtual machine should start without any errors now.
