Would this be consistent with the PIT taking longer to respond? The mode of KVM used here (mentioned on the KVM list) moves the PIT to userspace and would make it less accurate. If I'm reading OpenBSD's LAPIC calibration code right, this might be the case. I believe Linux uses one of the PM Timer or TSC to do the calibration.
(The obvious solution here is to just disable that mode if you are using OpenBSD, which apparently works.) -- Sent from: http://openbsd-archive.7691.n7.nabble.com/openbsd-dev-bugs-f183916.html
