[Libvirt-cim] [PATCH 1 of 2] Add an EmulatedType field to DiskRASD to select CDROM or Disk

[Dan Smith]

JF> After thinking about this more (and taking another look at
JF> CIM_RASD), couldn't the existing ResourceType CD Drive or DVD
JF> drive be leveraged instead of adding a new property?

I went down this path a few weeks ago, which ended in frustration and
patches sitting in my tree for a while.

Because of the way we correlate things, we end up having to change the
implementation of a lot of bits to handle that new ResourceType all
the way through the stack.  Every time I tried to compress Disk,CD to
Disk, I'd find something further down the stack that expected them to
be separate.  ResourcePools, Devices, etc.

Now, that's not a good justification for deciding how the model is
designed, for sure, and it's definitely doable.  If the preference is
for this method, then I can revert the patch and we can go for the
more heavy-weight option.  I probably won't have time to finish my
half-complete set for a while though.
