Subject system VM looking for cloud0 bridge when OVS/GRE isolation is enabled
Date Tue, 01 Jul 2014 16:19:55 GMT
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?
