[Users] Ovirt Host (3.0) compatability issue with Cluster (3.1)

Hello All, I am new to Ovirt and trying to Implement Ovirt in my organisation with an view to implement complete open source virtualization solution instead of using VMware or other Paid once. I have installed ovirt-engine on Fedora 17 and have installed Ovirt node (Hypervisor) - Red Hat Enterprise Virtualization Hypervisor release 6.2 (20120510.0.el6_2) Post installation engine started fine but while trying to add host its giving me error as below. Host host1 is compatible with versions (3.0) and cannot join Cluster Default which is set to version 3.1. I don't know what exact details I would need to share for troubleshooting. Hence I have attached a file with details of rpms installed on ovirt-engine and node. ( One may not like to scroll the entire file) I might be missing something very silly or I may sound too stupid. Ovirt masters : Please guide. Thanks in advance, Keyur
