https://bugzilla.redhat.com/show_bug.cgi?id=1139766 Thing is, for some reasons you can have your domain's RTC to be in something different than UTC. More weirdly, it's not only time zone what you can shift it of, but an arbitrary value. So, if domain is configured that way, libvirt will correctly put it onto qemu cmd line and moreover track it as this offset changes during domain's life time (e.g. because guest OS decides the best thing to do is set new time to RTC). Anyway, they way in which this tracking is implemented is events. But we've got a problem if change in guest's RTC occurs and the daemon is not running. The event is lost and we end up reporting invalid value in domain XML. Therefore, when the daemon is starting up again and it is reconnecting to all running domains, re-fetch their RTC so the correct offset value can be computed.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
