Overview of the Issue

I encounter the same issue as the one described here (7312). (which is closed - i've tested all the workaround shown there)

Every time I create an image on Openstack, it is get deleted at the end of the process. Here is the basic output of the packer command. We are using VMware as OpenStack backend. If I run the packer build with '-debug' option, the image creation is successful.

It looks like from the Nova logs that there is a race condition in which vmware snapshot get deleted before the image upload completes and when we run with debug, there are few secs delay while we hit enter multiple time. Can we introduce a pause before the "Terminating the source server" step or do more check to make sure image is created successfully?

it reads like packer only looks at the image and when it's available, while there's an endpoint in Nova for checking if an asynchronous task is done.
