Hi, I've some Windows 10 1803 guests on my clusters. They're totally idle (according to the windows process manager) but on the host side they consume a lot of CPU, between 6% and 15%. All the windows installations are fresh installations, with tablet disabled, ballon and qemu guest agent. I've disabled all options (balloning, guest agent, ...), but the problem is still present. I don't understand why the idle windows VM are consuming a lot of CPU. The problem is not present on linux guests.
