I'm using linux on dom0 and in all my domU.
If I do a shutdown wih the command "halt" then xm list doesn't show my
domU so I think it is destroyed.
However I do a shutdown, with xm list I don't see the domU, renamed
logical volumes, changed the config file and do a xm create VM.cfg.
After a while domU starts and it seems all ok.
