Review comment:
       @rhtyd y, mv is faster, however for configdrive ISO, if it is attached 
to a vm, it will not be recognized in vm after "mv"
   there is no issue if "cp" is used.
   
   I am thinking about (1) not change this script, but copy configdrive ISO in 
java instead of calling this script (createvolume.sh); (2) detach and re-attach 
configdrive ISO when it is changed.
   
   this is a draft PR, still WIP.
