Hey Guys,

I am on openstack newton. running compute agent on windows hyperv. The unused base images are keep getting deleted. However I have enabled this option in Nova.conf on compute: removeunusedbase_images=False

There's nothing in the log, do I have to enable the above option in controller server as well? I don't know what is deleting them and where to start checking.

Looks like this is a bug, we'll send a fix as soon as possible. Thanks for bringing it up.

For the record, here's the bug report:

As mentioned there, one workaround would be to set "remove_unused_original_minimum_age_seconds" to a really large value (e.g. 2^30). Setting it to -1 won't help either.

Regards, Lucian Petrut

The above worked after I disabled image cache manager itself. Added below line to nova.conf on my compute node:

That would work as well. The only issue may be the fact that image timestamps won't be updated anymore when being used by instances, which may help if you change your mind at some point and want to re-enable image cleanups.
