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?
This should be caused by the MOM daemon, which periodically checks the availability of Vdsm. Bests, -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani
