Issue/Introduction
After an upgrade of XenServer, Virtual Machines (VMs) will not start with the following error:
Error: Starting VM 'Name-of-VM - This operation cannot be performed because the specified VDI could not be found on the storage substrate
Additional Information
Often, the issue occurs because of DVD not set to empty before upgrade of XenServer from one version to the next. Other times, the CIFS or NFS ISO library is no longer available, or possible VM was using the physical DVD drive, which is now empty. It is best practice to set DVD drive to empty when VM no longer requires access to ISO or physical DVD drive.
