Oracle VM VirtualBox is a free x86 virtualization hypervisor developed by Oracle Corporation. It can be installed on a wide range of operating systems, including Windows, macOS, Linux, Solaris and OpenSolaris. However, if you run it under Windows, you may get the following error message: Raw mode is not available on Hyper-V (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT).

What causes `Raw-Mode is not available on Hyper-V’?

The main reason for the error message Raw-Mode is unavailable courtesy of Hyper-V is the fact that Hyper-V is enabled on your machine. This proprietary virtualization technology from Microsoft allows you to create virtual machines on x86 and x64 systems running a proprietary version of Windows.

A popular scenario that can cause this problem is when the HyperVisorLaunchType service is set to AUTO. This forces your system to check for applications that use VT-x before starting each virtual machine.

Another possible cause of this problem is that hardware virtualization is disabled in the BIOS or EUFI settings. Please note that virtualization is now enabled by default on all newer hardware, older computer configurations may not have this option enabled by default.

The software that powers Windows and many server operating systems has a feature called raw mode. In raw mode, the software’s host operating system uses the full power of the CPU by running “virtualised” applications. There’s nothing to stop the virtualised applications from writing to disk or even crashing the host operating system. But sometimes, when a virtualised application crashes, it makes the host operating system inaccessible, sometimes known as the “Hyper-V” or “raw-mode is unavailable” VirtualBox problem..
