[ovirt-users] cloud-init options under python-sdk

[Amedeo Salvati]

hi Juan|guys,

thanks for hints! but unfortunatly it seems wont works, because I've launched vm with this simple code:

action = params.Action(vm=params.VM(initialization=params.Initialization(cloud_init=params.CloudInit(host=params.Host(name="rheltest014")))))
vm.start( action )

but after boot the VM, cloud-init service hasn't set hostname and on cloud-init.log and cloud-init-output.log I cannot find any entry for setting hostname, instead if I use web ui it work's fine...

there are any ways to debug cloud-init jobs?
the params params.Host is right for CloudInit host or is intended for host / hypervisor?

Best regards
Amedeo Salvati
