I run Symmetricom S300. I would like to use Sysplex to manage the time on my mainframes. Could someone point me to some documentation? Thank you. Richard

So, you are trying to run ntp-4.2.2pl-9 on CentOS (v ?) in a Microsoft's Virtual Server (2005 ?) on windows 2008? Microsoft & CentOS would clearly be the places to ask about your unique needs. A little research shows REHL (where CENTOS is ripped off from) has several recommendations depending on the version of REHL of kernel parameters that need to be set to get NTP to run properly on REHL in a VM. disable_lost_ticks, clock=pmtmr, divider=10, clocksource=acpi_pm, ... They also recommend tinker panic 0 # Must be at the top of the ntp.conf file server 192.168.0.1 # Whatever the IP of the host OS is as seen by virtual OS # Make sure the firewall permits NTP between the virtual OS and the host OS # disable CPU power management M$ seems to have notes on the subject, among them: <http://support.microsoft.com/kb/918461> M$ seems say they have solved it in Hyper-V: Linux Integration Services Timesync: The clock inside the virtual machine will remain synchronized with the clock on the host. <http://blogs.technet.com/b/virtualization/archive/2010/07/29/linux-integration-services-v2-1-now-available.aspx> I think you have your solution. -- E-Mail Sent to this address <[email protected]> will be added to the BlackLists. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
