Cannot configure network inside virtualbox

I cannot set up BIGIP-13.0.0.0.0.1645.LTM-ide.ova. I followed the steps described here : https://devcentral.f5.com/articles/why-the-big-ip-ve-ova-does-not-work-on-virtualbox-19585 , to properly launch the virtualmachine. But i still don't think it's properly configured. Network configuration: As you see eth0 is not properly ipv4 configured. What could be the problem?
