I'd only be in favour of enabling it if there is some clear time frame on whicht hat bug above is likely to be fixed. I'm guesing it is pretty unlikely to be fixed before our freeze, so I thinking speculatively enabling it is premature.
I'm not sure. Kevin, any idea when we can expect the fix?
Otherwise the only option to enable blockdev would be to just enable it and blame qemu for internal snapshots not working.
The main problem with implementing a fix was that it's unclear what the desired result even is. After some discussion with Max, I think we'll try it with restricting snapshotting to everything that is directly attached to a BlockBackend and monitor-owned nodes that don't have any parents.
Yes that is what I would expect as well, and possibly also consistent with a 'drive_add with if=none' being used but not the corresponding -device. (thus no frontend).
