Some users want to use different operating systems in a single computer. But run multiple operating systems is not possible. That’s why manufacturers are developed VirtualBox.

VirtualBox is one of the well-known and popular virtualization tools that work for both x86 and x64 architectures.

When we try to run the Virtual Machine on our desktops, we see this Not In A Hypervisor Partition (HVP=0) (VERR_NEM_NOT_AVAILABLE).

It is a commonly occurring problem and is faced by several users. With a simple fix, we can solve it and run the virtual machine error-freely.


Problem Overview

Oracle Corporation developed this Oracle VM VirtualBox for free of cost. It is an open-source hosted hypervisor designed for x86 virtualization. In the year 2008, Sun Microsystems took over this VirtualBox. Later in 2010, Oracle again acquired it.

We can download and install this VirtualBox on Windows, macOS, Solaris, and OpenSolaris. We have to allocate a certain memory space on our hard-disk to install it.

Using this VirtualBox, we can install a secondary operating system. For example, if you have installed Windows OS on your main memory, you can set up Mac or any other supported operating system on this VirtualBox.

By this, we can run all those applications that are compatible with both Windows and Mac on a single host. But there are some drawbacks of VirtualBox.

One such problem is Not In A Hypervisor Partition (HVP=0) (VERR_NEM_NOT_AVAILABLE). Whenever we try to start the virtual machine, we see this error message on our screen.

Along with the error message, it also displays the reasons for this cause. They are:

  • VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).
  • AMD-V is disabled in the BIOS (or by the host OS) (VERR_SVM_DISABLED).

When this error occurs, we can’t use the operating system installed on the virtual machine. That’s why we have to fix it as soon as possible to run the virtual machine perfectly.
