I don't need heavy encryption for my VM - just to keep others out should the computer be stolen. I want to turn off FileVault on the Mac, so it can boot and automatically login a user (e.g., in case of power interruption), but I want to keep my email, docs, photos, etc. secure. So I created a VM running Yosemite to put all my personal info into. Which is the preferred approach, turning on FileVault in the VM or turning on Parallels' encryption?
