This is 100% exactly the reason why we recommend using the generic
images for OpenStack. The fact that there are hundreds of independent
OpenStack providers around the world, all of which may choose to present
their own VM device model, is exactly why we don't try to target them
with the cloud kernel. Use the generic kernel in the generic images and
be happy. It all works.
I'm not sure where the confusion lies.
