We've just deployed a Windows 2008 server with 3 virtual test servers running on it. Applying updates to the virtual machines and rebooting them if necessary is pretty straightforward. How to apply updates to the host server and rebooting it is our concern. Is there any way to handle the state of the virtual machines when rebooting the host?

Yes, I know this is an old post, but Im trying to clean them up. Did you solve this problem, if so what was the solution?

I personally just let Hyper-v Handle it, however I something will pause /shutdown VMs just because and manually restart them once everything is back up.
