Virtual Machine Manager Error 801


I recently ran into a problem when deploying new machines either from a template or a “empty” machine


Error 801 Ensure the library object is valid and then try the operation again , looking at the library server there was access I could open the files no errors at all.

Bing Search to the rescue

When performing any operation on a virtual machine (VM) in System Center 2012 Virtual Machine Manager (VMM), the job fails with the following error:
VMM cannot find the Virtual hard disk object’ error 801

That sounds like a spot on match


Backup VMM Database

Stop VMM Services

Run SQL Script

Start Services


And we back in action.

Not quite sure what caused the issue will try to look if I see it again.
