Hi, 

         I setup a breakpoint in Line 637 in bindingxmlrpc.py , which as
follows:  (branch:4.0; code url is:
https://github.com/oVirt/vdsm/tree/ovirt-4.0)

636  def ping(self):

637     api = API.Global()

638     return api.ping()

 
         But even the vdsm is not managed by any ovirt-engine ,  the line
637 will be called many times, 

 
         I thought the ping() function will be called only when the
ovirt-engine will create connection with vdsm, so why it will be called
cycle?

 
Thank you
