Does Genymotion Desktop on Windows require VirtualBox or QEMU?

VirtualBox is the default and recommended hypervisor on Windows for Genymotion Desktop. On Linux and macOS, QEMU is the recommended hypervisor instead. If you are on Windows and seeing VirtualBox host-only network errors, the issue is usually with the VirtualBox adapter, not Genymotion itself: Windows - An error has occurred while trying to create a virtualbox host-only network interface and Get Started with Genymotion Desktop.

On Windows, Genymotion Desktop uses VirtualBox by default, and Hyper-V can cause crashes or very slow performance. For Android 15 and 16, VirtualBox is not a good choice and QEMU is recommended instead: The Virtual device takes a very long time to boot and is very slow.
