Comment 23 for bug 1496927

Joe, be aware that the vss daemon for Hyper-V only supports host versions 5.0 and greater. As a result, it won't actually *do* anything on Windows Server 2012. I'm not sure what the underlying issue is, but is it spinning in an attempt to start the daemon? This really slows down our VMs and we do a lot of testing so it would be really good to figure out what changed to cause this behavior.
