I am running a single host with 2 guests. Each guest has Windows 10, 1xSSD, 1x7200RPM HDD, and 1x GTX970 SSC fully passed through. What can I do to optimize my power usage. Obviously if I put one vm to sleep\shutdown the full box doesnt go into hibernation. Do the HDD's and GPU go into power save when the guest isnt running. Is there anyway to where if both VM Guests are in standby the host goes into like a WoL or something. My goal is to replace mine and my wifes physical boxes with 1 physical box for both of us to use, my goal is to optimize power use (if possible), save physical space, and do something not so commonly practiced.
