Created attachment 1220225 [details] log files Retest with redhat-virtualization-host-4.0-0.20161107.0, not the exactly same issue “switch host to maintenance failed" occur, so attach the logs and hope they are helpful.
From the screenshot: the "Log out"-link is rendered but the dialog states the Login is missing. This might be caused by too fast click on "Host to maintenance" after engine login, so the dialog is rendered before previous action is finished. Anyway, the UI in the background is updated right after the Login action finishes, no matter of the dialog. Or there was a network issue, so the REST API was not accessible for any reason. In both cases, I see that as WONTFIX. Please reopen if you can reproduce in different scenario and the issue has impact on the user workflow.
