Comment 1 for bug 1881592

the test is not correct

https://github.com/openstack/tempest/blob/348fa311fe031ff7d04f41aa9e6ac65f6f6391fe/tempest/api/compute/images/test_images_oneserver_negative.py#L109-L114

is a race.
if the first image saves quickly or has not started yet then the second call can succeed without raising an exception.

we should likely remove this form tempest and instead test this with a functional test in nova as we will not be able to reliably gauntee the image will still be saving in tempest.

i suspect this only passed because of slow performance of glance/nova in the gate.
