404 when starting RHEVManager via Webbrowser

Hello,

I installed RHEL and RHEVManager.

I can open Webside https://virtm.intern:8443/ and see

Welcome to Red Hat Enterprise Virtualization Manager.

Version 3.0.0_0001-51.el6 Portals (...)

When I go to https://virtm.intern:8443/RHEVManager I got an 404 Error:

HTTP Status 404 - /RHEVManager

type Status

report message /RHEVManager description The requested resource (/RHEVManager) is not available.

JBoss Web/2.1.12.GA-patch-01

Same without hhtps and for all other links on the portal. Seems that there is no host configured but I don't know where to find something like httpd.conf at RHEL. Or any other idea what I have to check/correct?

Thanks, Thomas Wild
