Getting VirtualBox ready with Android X86 and ARM without emulator

How is it possible to get VirtualBox ready with an Android-x86 ISO image which supports ARM v7 (armeabi-v7a)? Genymotion seems to do that, but as soon as I start the VirtualBoxfrom VirtualBox, it does only display the terminal. Same with all the other Emulators like AndyRoid. I've tried installing several x86 ISO images. Installed the ARM translator (libhoudini) and so on. I've tried to install the Buildroid image, same results. Some games work, but Clash of Clans doesn't. This is what I'm pointing at. Clash of Clans needs ARM v7. v5 does not work in this case. Has anyone ever handled installing Android X86 with ARM v7 or a way accessing the VirtualBox from Genymotion without GenyMotion?
