hello guys!
I'm writing some python code to start VMs, and based on operating system
(at this moment centos6 nad centos7), I would like to use cloud-init
options (available on web ui at run-once) to start them and resetting
root password, change hostname and write some configuration files by
using yaml semantics, but at this moment I was unable to find a way to
do it...
somebody know a way (or could send me some hints) using python-sdk to
start A VM and pass to it cloud-init options?
e.g. the portion of code I would like to change is vm.start() under rhel6|7:
try:
                osVersion = vm.get_os().get_type()
                if (osVersion == "rhel_6x64" or osVersion == "rhel_6" or
osVersion == "rhel_7x64") and CLOUDINIT == "yes":
                    print "Starting VM: " + vm.name + " with cloud-init
options"
---->                    vm.start()              <----------
                else:
                    print "Starting VM " + vm.name
                    vm.start()
                while vmstat != 'down':
                    sleep(1)
                    vmstat = vm.get_status().state
            except Exception, err:
                print "Error on starting VM"
                print err
Best regards

It should be something like this:

  from ovirtsdk.xml import params

  action = params.Action(
    vm=params.VM(
      initialization=params.Initialization(
        cloud_init=params.CloudInit(
          host=params.Host(
            name="myvm"
          ),
          users=...,
          files=...,
          ...
        )
      )
    )
  )

  vm.start(action)
