        I have recently done a number of bad things to my XCP 1.0 environment. 
I believed most of them sorted. Then I upgraded from XCP 1.0 to 1.5 by way of 
1.1. The bad things involved moving the shared storage backend from NFS to 
Glusterfs, monkeying with the SR and its PBD's, losing all the vm vbd's in the 
process having to manually find and remap the VDI's to the correct VM. Once I 
survived all of that self induced unpleasantness, I decided to upgrade to 
1.5.... (obviously a genius behind this keyboard) After the upgrade some VM's 
boot and run as before, but others attempt to boot, then the console shows the 
subject message and shut down after 30 seconds. Please note that the 
functioning VM's are from the name SR/PBD as the non-functioning ones. Also, I 
can attach the non-booting vdi's to Dom0 and mount/fdisk them without issue. My 
question is: how do I further interrogate / investigate this boot process 
failure and success to ID the source of the issue?

        Thanks very much in advance.
