created a little cloud with a host and two worker nodes using opennebula. The setup went 
successfully until now, I am able to create VM's and move them via 
normal and live migration.<br>Another (possibly) important information is that I configured my virtual bridge on both worker nodes like this:<br><br></div><pre> auto br0
