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.
Bests,
