Upon rethink, that not strictly true, there's still the existing
metadata service that works across all hypervisor drivers. I know
we're far for feature parity across all virt drivers, but would
metadata-over-vsock be acceptable? That's not even lack of feature
parity, that's a specific feature being exposed in a different (and
arguably worse) way depending on the virt driver.
