Resolution1. SmartMouse does not work
User has to release a keyboard and mouse to return the input back to the host. Thereby drag and drop operations work only in the "host-to-guest" direction. Drag and drop from guest to host does not work.
2. Dynamic resolution does not work
Resizing of a VM window does not result in automatic changing the screen resolution in guest OS: either black border or scrollers appear around the Virtual machine desktop image.
User has to adjust the guest screen resolution and VM window size manually.
3. Windows Aero Interface, 3D operations (DirectX, OpenGL) and Coherence mode are not yet supported in Windows 8 Virtual machines.
