Hi, is it possible to create a guest VM by cloning my current active Yosemite OS? I've not had any luck upgrading a Yosemite guest VM I manually created to El Capitan, and wondered if I can clone my current system, I could then upgrade the cloned VM to El Capitan and give it a road test. Will it be possible to clone Yosemite and create a guest VM out of it? Thanks!
