Adding oVirt 3.4 support

Tested with oVirt 3.4. Make sure you have 4 gigs of RAM and bare metal. Works
well with nested KVM virtualization.

All remarks done, except this one. I don't want to explicitly exit.
Another tests will fail. Maybe you want to setup oVirt manually and
still to run this test suite.

Will push the changes. Good points. Note there is one bug - the answer
file is missing one option, therefore the installation freeze (asking
for input). Filed a BZ for that:
