[Users] Problems using the PythonSDK

Tue Jun 4 13:05:19 UTC 2013

Hello everyone!

I´m almost done with Python for now. But the last thing I sitll can´t seem to get any hang on is how to change the name of a VM´s disk:

>>> from ovirtsdk.api import API
>>> from ovirtsdk.xml import params
>>> api = API(url='https://${OVIRT}:443<https://storm.slu.se:443>', ca_file='/etc/pki/ovirt-engine/ca.pem', username='admin at internal<mailto:'admin at internal>', password='letmein!')
>>> VM_NAME = 'FedoraTest'
>>> DISK_NAME = '%s_Disk1' % (VM_NAME)
>>> vm = api.vms.get(VM_NAME)
>>> vmdisk = vm.disks.list()[0]
>>> vmdisk.alias = 'foobar'
>>> vmdisk.name = 'foobar'
>>> vmdisk.update()
<ovirtsdk.infrastructure.brokers.VMDisk object at 0x25d7ad0>

But the name/alias/whatev never changes...

Could you please give me an exact, and working example of how to change the name of a VM´s disk. This is the last simple thing I would like to accomplish before sharing a little something back with y´all(teaser, teaser).

Hi,

Lets follow http://www.ovirt.org/Python-sdk

In [1]: from ovirtsdk.xml import params

In [2]: from ovirtsdk.api import API

In [3]:

In [4]: api = API(***, ***, ***)

In [5]: user_name = "***"

In [6]: domain = "***.***.***.redhat.com"

In [7]: user_domain = params.Domain(name=domain)

In [8]: user_name = "{0}@{1}".format(user_name, domain)
# creating user
In [9]: new_user = params.User(domain=user_domain, user_name=user_name)
# adding user to users resource
In [10]: user = api.users.add(new_user)
# adding role to user
In [11]: user.roles.add(api.roles.get('UserRole'))
Out[11]: <ovirtsdk.infrastructure.brokers.UserRole object at 0x30c7590>

Thanks
Ilia

It should be like:

from ovirtsdk.xml import params
from ovirtsdk.api import API

api = API('*', '*', '*')
vm = api.vms.list()[0]
user =  api.users.list()[1]
role = api.roles.list()[1]
permit = params.Permission()
permit.set_role(role)
permit.set_vm(vm)
user.permissions.add(permit)
Thank you very much, I´m going to test this out today! Could you also show me how to first add a user that isn´t in the system yet, please?

Hi,

We have several tests like:
"Add VM permission to user", that are using ART's art/rhevm_api/tests_lib/low_level/mla.py addPermitsToUser function.
This is generic function but it shouldn't be hard to prepare SDK code with the same functionality.

Thanks
Ilia

this kind of call is not efficient, by fetching the disk
you also fetch the vm,

i'd suggest fetch vm, store it in local variable and then
reuse it for any sub-collection manipulations.

disk.name is deprecated, please use 'alias' instead.

elena, ilia,

guys, do you have any permission related code to share?
