[Engine-devel] RFC: is it possible to configure hosts in cluster to be NTP peers

Hi, ovirt still doesn't configure NTP on host installation and relies on administrator not forgetting to set it up correctly, mainly because it is quite hard to configure it correctly automatically. There is one thing IMO that could be configured automatically and that could alleviate situation somewhat: make hosts in the cluster NTP peers so that when clocks go wrong in the cluster for any reason, the error is the same on all hosts in the cluster. The files could be stored in /etc/{ntp,chrony}/vdsm.conf for instance and referenced with includefile or include ..." in /etc/ntp.conf or /etc/chrony.conf respectively. What seems tricky though is that non-Up hosts should be excluded from peer list because there are higher chances that their clocks are not configured properly, so engine (or some host?) should trigger changes to NTP configuration pretty frequently. What do you think about these issues? I don't want to report bugs/RFEs on topic before I'll see your reply.
