Can you please elaborate on this? Is the balloon driver *used* by
the
storage driver so that the latter won't work without the former?
What
will happen if the virtio-balloon device isn't configured in the VM?
It's just that without the virtio balloon driver installed, the virtio
block one won't start properly, resulting in the famous 0x7B error.
Or is it just a matter of ordering of the balloon driver within the
driver start sequence, so that it can get its hands on the system as
early as possible for its own purposes, and the storage driver
doesn't
require balloon's presence?
It's not ordering, it really requires it.
