To install the symbol maps please run the following command on the machine running the engine (or VM if it is HE). yum install ovirt-engine-webadmin-portal-debuginfo Please restart the ovirt-engine process with systemctl restart ovirt-engine after you have installed the symbol maps. Then next time you see the message in the UI, the stack trace in the log should be readable and we can help you better determine what is causing the problem.
