NTP Viprion (VCMP)

Question

Hello,&nbsp;We have a Viprion with several guests running on it. I wonder is it really necessary to define NTP servers on the guests or is it syncing from the clock of the VCMP host&nbsp;Without NTP servers defined on the guests I have this.&nbsp;# ntpq -p&nbsp;&nbsp;remote&nbsp;&nbsp;&nbsp;refid&nbsp;&nbsp;st t when poll reach&nbsp;delay&nbsp;offset jitter==============================================================================*LOCAL(0)&nbsp;&nbsp;.LOCL.&nbsp;&nbsp;&nbsp;10 l&nbsp;23&nbsp;64 377&nbsp;0.000&nbsp;0.000&nbsp;0.001&nbsp;slot1&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;-&nbsp;64&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;slot2&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;-&nbsp;64&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;slot3&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;-&nbsp;64&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;slot4&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;-&nbsp;64&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;With NTP servers defined on the guests I have this.&nbsp;&nbsp;# ntpq -p&nbsp;&nbsp;remote&nbsp;&nbsp;&nbsp;refid&nbsp;&nbsp;st t when poll reach&nbsp;delay&nbsp;offset jitter==============================================================================*10.x.xx.x&nbsp;&nbsp;1xx.yyy.eee.ee0 3 u 331 1024 377&nbsp;&nbsp;0.796&nbsp;1.061&nbsp;1.387+10.x.xx.y&nbsp;&nbsp;1xx.yyy.eee.ee1 3 u 745 1024 377&nbsp;&nbsp;3.907&nbsp;2.364&nbsp;2.330+10.x.xx.z&nbsp;&nbsp;1xx.yyy.eee.ee0 3 u 567 1024 377&nbsp;&nbsp;1.082&nbsp;0.773&nbsp;1.643&nbsp;slot1&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;- 1024&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;slot2&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;- 1024&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;slot3&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;- 1024&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;slot4&nbsp;&nbsp;&nbsp;.INIT.&nbsp;&nbsp;&nbsp;16 u&nbsp;- 1024&nbsp;0&nbsp;0.000&nbsp;0.000&nbsp;0.000&nbsp;Anyone a hint ?&nbsp;Thx in advance.Luc

Hello Luc&nbsp;Yes, it is necessary to define NTP servers on the guest. The guests are supposed to be pretty much 'independent' boxes like when you create a new VM on VMware for example.&nbsp;If you need NTP on the guests, forget about the host and set them there.&nbsp;Thanks,Rodrigo&nbsp;&nbsp;
