Comment 4 for bug 1824858

I wasn't able to reproduce this on Nova master. I have vague memories of something like this being reported in older versions, but having been fixed since then, though I can't find hard evidence in the shape of bug reports and/or reviews. I'm going to leave this as Incomplete until we get more information, in the shape of:

- what version of Nova can this be reproduced for?
- more detailed reproducer steps - perhaps a specific storage configuration is needed.
