        Propose: allow user to edit cache, io and bus for each disk Make cache and io part was easy, but i got big trouble to change bus Questions: 1) How we are going to change the bus? Got some issues aroud: A) How to determine available bus? I know there is a function, but is it works with vms with different buses? B) From OS perspective? How can we deal? Only let the user choose the driver on creation, not update?
