I'm not too sure how much that would help anybody. It would probably go something like this: 1) Timekeeping in VMs sucks, but out of necessity. The timing hardware is virtualized inside each guest, and each VM only gets "slices" of real CPU and wall-clock time, so timekeeping is difficult. 2) The process by which the timing hardware is virtualized is implementation-specific. VMware Server, WMware ESX, Xen, Hyper-V, KVM, etc. all do this a little differently. Consult your virtualization software's documentation for best practices regarding timekeeping inside virutalized guests. Some may have custom drivers or other tools to help. -- RPM _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
