Running NTP everywhere wakes every guest up periodically, so you waste a fair amount of cycles waking up to do nothing for most guests.
The clocks in Linux guests do drift slightly (even if the HW is synced to STP) -- it's order of tenths of microseconds, but it does lose a little (barely measurable) bit. The things that really care about time (like any service using Kerberos security, or other things that use time as a salt in some other process) need NTP because they don't work without completely accurate time. Everything else can get along fine with running ntpdate once a day. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
