We updated our 2 Hyper-V host servers with all latest patches. The VM's are running, but you cant copy VHD templates over to Host to create new VM's any longer. You also cant apply a snapshot. Just applied a snapshot to 1 of my VM's and now the VM is broken. It wont start up, roll back or forward.
It just says "Starting" in the HyperV manager and there is an error on screen " An error occured while attempting to apply the snapshot. The computer 'localhost' failed to perform the requested operation.
