With 4.1.0, this issue has been corrected for both the VMware vSphere and KVM system VM flavors via post boot configurations.  The XenServer system VM template does not have an official fix for this problem.  If you choose to take advantage of the new S3-backed secondary storage feature while running your system VMs on XenServer, you may be impacted by time synchronization issues.</para></entry>
