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
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?
