<br>
We have an issue [1] in python-novaclient 2.32.0 where it's not working with rackspace cloud.<br>
<br>
It's caused by a commit [2] that changed the default requested compute API version from "latest" to "client supported latest", a specific version. We have some logic in the discover_version method that does comparisons between a user-specified version and the server version. For rackspace, we get a "null" server version because the version list API isn't exposed. The discover_version falls back on compute API 2.0 when requested version is "latest" and server version is "null" but raises an error when requested version is "user-specified" and server version is "null". So more work is needed there to handle cases where version API isn't exposed.<br>
<br>
Should we revert [2] for now? Any other thoughts?<br>
<br>
Thanks,<br>
