XenCenter doesn't give VM-Name/UUID on shutdown problem

When rebooting an XS host, XC may show "VM didn't acknowledge the need to shut down."
It says which Server is affected, but doesn't name the VM. XC should really be more informative!

We had the lack of informations given in the event tab already a while ago, IIRC it was about VHD not found, which was, in final, just a mounted Image to the virtual optical drive.
