Comment 46 for bug 1221190

I have the same thoughts as Nikola on this - when I proposed this idea, I was certainly thinking of disks.info being a per instance file, not global to the entire host. As Nikola says it gives us saner cleanup on VM delete if we can just rm the entire file and not worry about doing string manipulation of lines inside a shared file. It also avoids having to acquire any global lock to protect the file. If an instances disk.info file gets corrupted that's fairly harmless, but if we have a single global disks.info file and that's corrupted the impact is pretty bad. So I'd rather prefer a per-instance file
