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

This should be caused by the MOM daemon, which periodically checks the availability
of Vdsm.
