If an NTP server is configured on the host, it is possible for libvirt-guests to start before the NTP service, in which case guest clocks won't be synchronized to the host clock.
Add ntp-wait.service to "After" in libvirt-guests systemd service file, ensuring NTP has synchronized the host clock before starting any guests.

Well, guest can have their own ntp-client (and in most cases they do, right?). I mean, since guests can be paused, saved & restored back, their time is often off. So the best is to have an ntp-client running inside the guest. Michal
