Title:
VMware: factor out the management of unit numbers
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
Virtual devices need a unit number when they are attached to a
controller. We cannot have two devices on the same controller with the
same unit number.
Currently, the selection of unit numbers is spread all over the driver
code, leaking to high-level functions like spawn() and rescue(). We
need to factor this out into helper functions which take care of
choosing a proper unit number and creating additional controllers if
needed.
High-level functions need to communicate only the intent like 'attach
CDROM' or 'attach disk' and shouldn't bother with details like unit
numbers.
