ovirt-node-3.2.1-6.el6.noarch


Test steps:
1. Clean install rhev-hypervisor6-6.6-20150128.0.iso
2. Login rhevh and press F2 to enter into shell console
3. Remove OVIRT_*VERSION parameter from the /etc/defaults/ovirt
4. persist /etc/defaults/ovirt
5. Reboot rhevh and check log info in /var/log/ovirt.log

After step5, could see exception info in /var/log/ovirt.log

2. Press F2 drop into shell, remove the OVIRT_*VERSION parameter from the /etc/defaults/ovirt
3. Persist /etc/defaults/ovirt
