Hey, What is considered "best practice" when running a KVM host with a mixture of Linux and Windows guests? Currently I have ntpd running on the host, and I start my guests using "-rtc base=localhost,clock=host", with an extra "-tdf" added for Windows guests, just to keep their clock from drifting madly during load. But with this setup, all my guests are constantly 1-2 seconds behind the host. I can live with that for the Windows guests, as they are not running anything that depends heavily on the time being set perfect, but for some of the Linux guests it's an issue. Would I be better of using ntpd and "-rtc base=localhost,clock=vm" for all the Linux guests, or is there some other magic way of ensuring that the clock is perfectly in sync with the host? Perhaps there are some kernel configuration I can do to optimize the host for KVM? I'm currently using QEMU PC emulator version 0.12.50 (qemu-kvm-devel) because version 0.12.30 did not work well at all with Windows guests, and the kernel in both host and Linux guests is 2.6.33.1 :o) /Thomas -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
