The initial installation did not cause any big problems. After logging in to the interface and trying to enable plugins, this just timed-out. I tried to manually start the plugins on the console (eg. /usr/lib/openqrm/plugins/dns/etc/init.d/openqrm-plugin-dns  start). This command started the plugin without any problem. Next I tried to configure select a volume group in the Plugin section (Storage -> LVM-storage-> Volume Groups). This also timed out with the error below in the http errorlog:

This error was caused by SElinux. After I disabled SElinux and rebooted the server, all functions of the OpenQRM interface worked fine, including enabling plugins and displaying volumegroups.
