You will notice there is no difference for a physical or VM, so in your case, set it
32 GB of RAM or more installed: 32GB plus 10MB (32,778MB)The paging file size is set that way so it you can get a full memory dump in case of a crash.
You do not absolutely have to set it that value, its just recommended.Hope that helps!
