This is bad news for me. Just got xntpd working for my Linux LPAR and was thinking about how things will work under z/VM. Does not z/VM run a virtual clock for the guests?
Would xntpd not work for the guests? __________________________________________
I believe the case that Chris talks about is a bug and should be investigated. We have not seen that in later kernels though. There is also a problem with SuSE if you do not specify in YaST that the hardware clock runs UTC (causes random time shift at boot).
Have a look at http://www.vm.ibm.com/events/nl77.pdf for the options.
Yes, you can run ntpd to keep your Linux server close to other clocks in the field, but you pay a price for that in overhead of idle servers. If your zSeries TOD clock is steered by a 9037 ETR you do not want to run ntpd because it gets confused. Be careful when you use ntpd on servers that are frequently rebooted when the z/VM time is slightly off.
