Hi ,
I have done below steps on node:
[root@node01 ~]# yum -y install
http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
[root@node01 ~]# yum -y install qemu-kvm libvirt virt-install bridge-utils vdsm
[root@node01 ~]# systemctl start libvirtd
[root@node01 ~]# systemctl enable libvirtd
So after this I have tried to add host through admin panel i.e Ovirt engine but no success
even tried with upgrading machine..
