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)

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 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?
