https://bugzilla.redhat.com/show_bug.cgi?id=1103245 An advice appeared there on the qemu-devel list [1]. When a domain is suspended and then resumed guest kernel is not aware of this. So we've introduced virDomainSetTime API that resets the time within guest using qemu-ga. On the other hand, qemu itself is trying to make RTC beat faster to catch the difference. But if we don't tell qemu that guest's time was reset via the other method, both mechanisms are applied resulting in again wrong guest time. In order to avoid summing both corrections we need to tell qemu that it should not use the RTC injection if the guest time is set via guest agent. 1: http://www.mail-archive.com/qemu-devel@nongnu.org/msg236435.html Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
