A. Typically, it's recommended that pagefiles be the same size as a system's total RAM. However, in a Hyper-V server with 128GB of RAM (which is mainly being used by VMs), do you need a 128GB pagefile? No, you don't need that much in the parent because the parent doesn't use it. So what should you use? A good rule is to use a pagefile size of 8GB, which will allow kernel dumps from the parent when needed.
