Share virtual disk between guests

Latest response

Is it possible to share virtual disk between two  guests ?

 

I'd like to  check if this  scenario  may be impelemted  :

 

  • run two rh5 guests
  • each guest has  one system disk
  • add second  virtual disk on  first  of these guests
  • defince some database on this extra  disk
  • Launch  db application on the first guest.
  • in a case of the db failure unmount/detach this  virtual disk from original  guest and  mount/attach it on the second guest  using API .
  • Run  db app  on  second guest .
