Hi,
just in case someone else runs into the same problem.
We were able to workaround this by using an alternate draft-iso image
kindly provided by fabian:
http://fedorapeople.org/~fabiand/node/ovirt-node-iso-3.0.1-1.0.2013100208...
if you want the fedora version it's:
http://fedorapeople.org/~fabiand/node/ovirt-node-iso-3.1.0-0.999.20131002...
We didn't test the fedora version.
This iso registers completly with Mangement 3.3 on the same host, no
more segfaults :-)
A big "thank you" goes out to fabian, who helped me debugging this.
Regards
Sven
