Hi, I am currently trying to attach Glance (OpenStack Image) and Cinder (OpenStack Volume) as external provider and am facing a problem when trying to use https in the Provider-URL on an ovirt 3.6 and 4.1 cluster. The Provider-URL I am using is in the form: https://<host>:9292 (or port 8776 for Cinder - <host> is either a fqdn or an IP-Address) Whenever I press the "Test" button in the "Add Provider" dialog I get the message "Test Failed (unknown error)." There is no entry in any logfile whatsoever (at least not in any logs that are associated with ovirt). I would expect an ssl cert dialog here. I can telnet to the destination ports from the engine and the nodes so Clance and Cinder are reachable I have also read that this might happen, if there is a corrupted /var/lib/ovirt-engine/external_truststore But this file is not even existing and when i create it by hand, it is not touched. How can I get this to work or even get an error message that gives me a hint where to look? Thanks for your support, Stefan
