This wasn't linked into the bug properly, but this change should resolve some of the problem here:

With that change, during server create, volume-backed instances won't have root_gb disk allocated against the compute node resource provider in placement, nor will it filter on root_gb disk (no "claim"). It's not a complete solution since it doesn't handle move operations that allocate resources on a new host like during cold/live migrate, unshelve and evacuate (well, at least not for existing instances anyway since their request spec wouldn't have the is_bfv flag set). But it's a step in the right direction. The only problem is, as currently written, it's not backportable to stable branches.
