Hello,
after some issues we were able to sort out some issues with the oVirt Engine Appliance.
http://jenkins.ovirt.org/job/ovirt-appliance_master_merged/lastStableBuild/
please see
http://www.ovirt.org/Feature/oVirtAppliance
for details on how to use and test the appliance.
Let me note - This appliance can be used with Hosted-Engine as well as
"standalone"
i.e. in libvirt, GNOME Boxes or in Engine itself. Depending on what you need.
Greetings
fabian
