info about support status for hyper converged setup
by Gianluca Cecchi 24 Aug '16

24 Aug '16

Is it now in version 4.0.2 (or previous 3.6.x) fully supported? Or still in testing? As described here: http://www.ovirt.org/develop/release-management/features/engine/self-hosted… Only with Gluster I presume... Is there any bug tracker to see a list of all potential problems/limitations or features not supported? Thanks, Gianluca

Can't upload disk image in oVirt 4.0
by Niksa Baldun 23 Aug '16

23 Aug '16

Hello, I am trying to upload a RAW disk image via web GUI. After a few seconds, it enters state "paused by system". I downloaded the certificate: https://engine-fqdn/ovirt-engine/services/pki-resource?resource=ca-certific… and installed it in browser (tried Firefox and Chrome), but it didn't help. My questions are: 1. What can I do to debug the problem, as there are no error messages nor entries in system log? 2. Is there an alternative way to import a disk image? Thanks, Nikša
