We've noticed our fully-virtualized KVM guests' time keeps getting faster, despite running ntpd. A quick google reveals this to be a known problem with virtual guests. It seems there are a variety of solutions, some apparently vendor-specific. What is the best practice as of now for KVM guests? * Setting independent_wallclock=1 (or is that a xen-only thing)? * Passing kernel parameters? If so, which? The vmware KB mentions "notsc divider=10" -- is that vmware-specific? * Just don't run ntpd on virtual guests? And let it get its time from the host. The last seems like the easiest/cleanest, if it really does always get its time from the host. Thanks for any info. johnny _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos-virt
