GPU Passthrough can be solved with LookingGlass (https://looking-glass.io/) if you just want a solve that particular problem. I'm not sure how well it works on a laptop but if you have a dedicated graphics card (e.g. Nvidia) you should theoretically be able to get it working the way you want. I'm sorry for the lack of elegant all-in-one packages. I too wish for an Excalibur of VM solutions.
