hello Juan|guys,
I still have problems with cloud-init options on python-sdk... now I'm trying to reset root password and according to xml available at http://www.ovirt.org/Features/Cloud-Init_Integration and specifically for user/pw:
... <users> <user> <user_name>root</user_name> <password>myPass</password> </user> </users> ...
I've changed action object with this example:
action = params.Action( vm=params.VM( initialization=params.Initialization( cloud_init=params.CloudInit( host=params.Host(address="rheltest025"), users=params.Users(
user=params.User(user_name="root", password="pippo")
Try to use a list here: user=[parms.User(...)]
) ) ) ) )
but when i try to start a vm I got this error: "TypeError: 'User' object is not iterable"
somebody has some hints for resetting root password?
Best regards 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
To change the hostname you have to use the "address" property of the "Host" class:
host=params.Host( address="myhostname.example.com" )
The "Host" class is used for many things, including CloudInit and hypervisors. But in this context it is just a container for the host name.
To debug cloud-init start the VM (with the GUI or with the RESTAPI), then go to the hypervisor where it is actually running, and look for the corresponding qemu-kvm process:
# ps -ef | grep qemu-kvm | grep myvm
The qemu-kvm command line will have a parameter indicating the file that contains the cloud-init data:
-drive file=/var/run/vdsm/payload/...img
Copy that file somewhere, then mount it and inspect the content:
# cp /var/run/vdsm/payload/...img /tmp/my.img # mount -o loop,ro /tmp/my.img /mnt # find /mnt ... # umount /mnt

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

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

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)
