@shlee@aus.social Yeah, IKR! Not sure, I think the guest rebooted faster but otherwise the same. That VM is idle most of the time. The power graph is for the whole host, which runs a bunch of little services as well as the HA VM! I would guess the difference is almost entirely qemu not having to run in userspace to check if the guest needs to wake up when it doesn't. Delegating all of that to the host kernel via KVM lets the CPU wake up less, and maybe even get into a lower P-state (speculating).
