I read this post before: https://forum.parallels.com/threads/high-cpu-usage-in-host-when-guest-is-idle.327992/ ~8.5% CPU for virtualization overhead plus 2% times 2 vCPUs equals ~12.5% host CPU usage, it should not be using the 30%~35% it's using now. My MBP 2011 is constantly running at 130 ºF and over. I'm using OS X Mavericks 10.9.5 and the latest Parallels 10.2.0. Can someone shed some light on this? Thanks!
