I should warn you that it's quite possible for GPU memory to leak into/out of VMs, the safety model is different. So the parent's horror story could absolutely happen to you.
- minimalist 4y agoI think that you are mistaken. In Qubes, none of the VMs have access to the GPU by default[0]. May you elaborate or provide some evidence to support your claim? [0]: Unless you do something "exotic" like pass the GPU through to a particular VM which is not supported and explicitly not recommended for the security reasons that you are thinking about.
