Do you have ssh keys or any other means to access the servers automatically?
What I'm thinking is that you could deploy the rabbitmq event notification message queue, and listen for create/destroy calls. I don't think you would be able to intercept the create call and alter it's runtime, but you could theoretically fire up a script that fetches the one time password, ssh into the vm and issues whatever command you need to register the vm with IPA. How you enable event notification varies on your cloudstack version, but this should be a pointer in the right direction: http://cloudstack-administration.readthedocs.org/en/latest/events.html -- Erik On Thu, Oct 30, 2014 at 7:36 PM, Yiping Zhang <[email protected]> wrote: > I envision to run these pre/post scripts on CS management server.
