   @weizhouapache @DaanHoogland 
   
   Thanks for the reply. I'm using a pre-built CentOS image, but it's not the 
image itself.
   
   My Cloudstack Agent log file is throwing an error, as I understand it, when 
trying to create a virtual router.

   I also attach the output of the "ip a" command to demonstrate the network
