Well, imagine domains were running, and as the host went down, they were managesaved. Later, after some time, the host went up again and domains got restored. But without correct time. And depending on how long was the host shut off, it may take some time for ntp to sync the time too. But hey, wait a minute. We have an API just for that! So: 1) Introduce SYNC_TIME variable in libvirt-guests.sysconf to allow users control over the new functionality 2) Call 'virsh domtime --sync $dom' in the libvirt-guests script. Unfortunately, this is all-or-nothing approach (just like anything else with the script). Domains are required to have configured and running qemu-ga inside.
