ntpd under Xen Dom0 exhibits extremely high jitter/noise? runs stable/quiet under non-xen kernel.
On a selection of boxes, ntpd running in Xen Dom0 reproducibly
exhibits extermely high noise/jitter.
Switching back to -default, non-xen kernel ntpd runs with very low jitter/noise.
Question -- how can I ''tame'' ntpd noise & jitter when running in Dom0?
Is the problem a config issue, or a bug?
Already reported this downstream; everybody''s "stumped".
