Which release of oVirt/RHV is it? We'd also need webadmin-debuginfo on the engine (+ ovirt-engine service restart to get a normal deobfuscated stack on ui.log file) (Originally by Yaniv Kaul)
Verified on rhevm-4.0.7.4-0.1.el7ev.noarch And thanks for video really helpful for the verification process :)
