When this happens, can you log into the affected VM (with the disk
"supposedly" attached) and paste the output of `xenstore-ls -fp
/local/domain/<domid>` (replace <domid> with the ID of the domain) here.
You will need the xen-tools package installed in order to do that.
It looks to me like this is some kind of issue with the XenServer
storage manager, so I would suggest asking this on the XenServer mailing
