Sorry, could you please explain in more detail?
Just "putting" the VBox D3D dlls into the guests system dir did not result
in any change concerning dxdiag - no D3D support.
Why should I install WineD3D on the host?
I expect, if it correctly installed on the guest, the calls are forwarded
via OpenGL to the host opengl - based on the opengl support already
available in vbox guest->host.
Yet, how do I correctly install WineD3D on the guest?

Thanks,
