Here's one of my systems, running ntpd on stable/11 r330228 on
XenServer 7.3, and there have been no issues so far. Timekeeping is as
good as can be expected. The XenServer host has Intel CPUs.
$ uname -aKU
FreeBSD somehost 11.1-STABLE FreeBSD 11.1-STABLE #0 r330228: Thu Mar 1
10:58:45 CET 2018 root@somehost:/usr/obj/usr/src/sys/XENGUEST amd64
$ w | head -1
2:18p.m. up 5 days, 1:23, 1 user, load averages: 0,18 0,20 0,17
Note, I run a custom kernel eliminating most of the unneeded stuff
when running as a/an Xen guest, see
