Openstack builder connects to wrong endpoint

[ghost]

This issue was originally opened by @JoelFeiner as hashicorp/packer#5201. It was migrated here as a result of the Packer plugin split. The original body of the issue is below.

---

I am attempting to build an image using the OpenStack provider. It ultimately fails at launching the server with the following message: "Error launching source server: Invalid request due to incorrect syntax or missing required parameters".

It is able to connect to the identity service, verify the flavor and set up the keypair (which might be a local thing).

One thing I am noticing is that tcpdump shows a lot of connections to ec2-54-235-77-197.compute-1.amazonaws.com, whereas when I launch the server with the nova client, there are none. I'm wondering if there's a hardcoded URL in Packer somewhere.

I'm unable to further debug this because Packer or the underlying library does not provide the response from the OpenStack server. From Googling, I see that this is simply not supported at the current juncture.

This URL may well be the one used by packer to look at hashicorp repository for newer versions available. PS: I personally can't reproduce this issue.
