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