https://access.redhat.com/documentation/en/red-hat-virtualization/4.0-beta/paged/rest-api-guide/chapter-2-authentication-and-security says Procedure 2.1. Obtaining a Certificate curl -o rhevm.cer http://[rhevm-server]/ca.crt [multiple occurrences of the http://[rhevm-server]/ca.crt URL below that] However, I believe that with RHEV 4.0 this URL is no longer correct and that it is now http://rhevm40.spice.brq.redhat.com//ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA (a compat redirect would have been nice to avoid unnecessary breakage at customers'...) At least the URL from the doc is not working with the test instance I'm using, and this other one is. Also, it's possible that the administrator has replaced the RHEV provided certificate with their own, it might be worth mentioning this caveat as well there.
Thanks, Christophe. We're currently tracking this change in bug 1353441. Feel free to add any additional comments there. *** This bug has been marked as a duplicate of bug 1353441 ***
