[ovirt-devel] moVirt setup error

Hi I'm really new to oVirt and basically plan to work on moVirt for which I'm setting up the engine. I'm running livecd of oVirt on my machine because of some reasons it's not getting installed in the virtual environment(after booting it shows a black loading screen which continues forever). I used VirtualBox on Ubuntu and gave 6gb RAM to the machine. I have abondened virtual environment as of now. Now I boot the OS with livecd, the engine setup completes successfully and I can open the localdomain and add new VMs but I get this error when logging in the app(screenshots attached). My laptop and mobile are connected to different LAN ports(different IP addresses). There's no option of connecting laptop to same wifi(no wifi enable option in ovirt). Can I get some help please. I'm totally new to the working of oVirt but I wish to learn and proceed. Thanks Neha
