I'm trying to get a VM time synced with a 64-Bit Windows 8 host upon host shutdown and startup. Linux Integration Services is installed on the virtual machine and all integration services are enabled and running. The issue is that when the host is gracefully shutdown, the VM is suspending rather than shutting down itself. When the host is then powered on, the guest resumes from it's suspended state and the guest's time is off by the time that the host was powered off. The only way that I can get the VM to match the host is if I have the "Automatic Stop Action" in Hyper-V Manager set to "Turn Off" which isn't good for the database. I'm experiencing this on CentOS 5.6 and CentOS 5.8.
