Re: [libvirt] [PATCH] libvirt-guests: wait for ntp service

On 08.09.2014 18:30, Jim Fehlig wrote:
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.
