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.
You can write this as follows:

```bash
cat > /tmp/ovirt-answers-file.conf <<-EOAF
    # action=setup
    ....
EOAF
```

Note that I used spaces here, but bash only understands tabs.
