system VM looking for cloud0 bridge when OVS/GRE isolation is enabled

Hi, I am trying to set up my cloudstack using OVS plugin.  I created an advanced zone with GRE isolation.  When enabling zone, system VMs cannot start with the following exception.  What did I miss?

Let me copy Murali in this thread. He is mastering on GRE feature currently.
