FWIW, we (Ceph) aren't complaining about the 6 month lag time (and I don't
think the Sheepdog guys are either).
>From our perspective, the current BlockDriver abstraction is ideal, as it
represents the reality of qemu's interaction with storage. Any 'external'
interface will be inferior to that in one way or another. But either way,
we are perfectly willing to work with you to all to keep in sync with any
future BlockDriver API improvements. It is worth our time investment even
if the API is less stable.
The ability to dynamically load a shared object using the existing api
would make development a bit easier, but I'm not convinced it's better for
for users. I think having ceph and sheepdog upstream with qemu will serve
end users best, and we at least are willing to spend the time to help
maintain that code in qemu.git.
