IMHO there's little value in just printing a warning. Until it actually goes away, people are liable to assume we're just being paranoid/awkward and keep using it anyway.I suggest crippling it now and, assuming noone steps up to fix+maintain it, ripping out the write support altogether at next release. I'm assuming the readonly code is in better shape, and can be supported with relatively little effort.
Yes, that's what I was getting at. We need to support read-only in order to allow people to convert to qcow2.
If we're sufficiently concerned that there is data corruption in the write path, we should disable it to keep a user from shooting themselves in the foot.
