Personally I don’t think
ansible and ovirt-shell are<br>
mutually exclusive.<br>
<br>
Those who are in ansible
and devops realms are not<br>
really<br>
scared by<br>
making python/ansible
work with ovirt.<br>
<br>
From what I gather,
playbooks are quite a de-facto<br>
pre-requisite to<br>
build up a real SaaC
“Software as a Code” environment.<br>
<br>
<br>
<br>
On the other hand,
ovirt-shell can and is a fast/easy<br>
way to<br>
perform<br>
“normal daily tasks”.<br>
<br>
totally agree but ovirt-shell
is deprecated in 4.1 et<br>
will be<br>
removed in<br>
4.2. Ansible or sdk4 are
proposed as an alternative.<br>
<br>
<br>
Could someone point me to an URL
where sdk4 is fully<br>
documented, as<br>
I have to get ready for
ovirt-shell deprecation?<br>
<br>
<br>
The Rest API is partially documented
under<br>
<a class="moz-txt-link-freetext" href="https://">https://</a><engine>/api/model .<br>
It's not complete yet. All new features
in 4.0 are documented and<br>
we are<br>
working on the 'older' features now.<br>
(contributions are welcome!)<br>
<br>
<br>
I'm sure no one at Redhat thought
about deprecating a tool in<br>
favor<br>
of a new one before providing a
complete user doc!<br>
<br>
<br>
In addition, the SDK RPM itself contains
many examples. See [1].<br>

Although these examples, I can successfully
create a snapshot, but I<br>
didn't find the way to delete it...<br>
Regarding many example, it should be
possible to locate any service by :<br>
name_service =
connection.system_service().na<wbr>me.service()<br>
<br>
So logically it should be doable with
snapshot like<br>
snapshots_service =
connection.system_service().sn<wbr>apshots.service()<br>
but : AttributeError: 'SystemService' object
has no attribute 'snapshots<br>
<br>
</blockquote>
In the SDK the services are arranged in a tree
structure that mimics the<br>
URL structure of the API. For example, if you
want to get the service<br>
that manages a particular snapshot, in the API
you would use an URL like<br>
this:<br>
<br>
/ovirt-engine/api/vms/123/snap<wbr>shots/456<br>
<br>
In the Python SDK that translates into this:<br>
<br>
snap_service = connection.system_service()
\<br>
.vms_service() \<br>
.vm_service('123') \<br>
.snapshots_service() \<br>
.snapshot_service('456')<br>
<br>
There is also a generic "service" method that
is useful when you already<br>
have all that path as an string:<br>
<br>
snap_service =
connection.service("vms/123/sn<wbr>apshots/456")<br>
<br>
Both return exactly the same object. The first
is usually better when<br>
you are calculating the path of the object
step by step, and I generally<br>
prefer it as it is less error prone.<br>
<br>
Once you have the reference to the service,
you can use the 'remove'<br>
method:<br>
<br>
snap_service.remove()<br>
<br>
If you need to search by the names of the
objects, then you can use the<br>
'search' methods, which are only available for
the top level objects,<br>
like VM, data centers, clusters, etc. For
example, to find your virtual<br>
machine and then the snapshot:<br>
<br>
# Get the root service:<br>
system_service =
connection.system_service()<br>
<br>
# Find the virtual machine:<br>
vms_service = system_service.vms_service()<br>
vm = vms_service.list(search='name=<wbr>myvm')[0]<br>
<br>
# Find the snapshot:<br>
vm_service = vms_service.vm_service(<a
moz-do-not-send="true" href="http://vm.id"
rel="noreferrer" target="_blank">vm.id</a>)<br>
snaps_service =
vm_service.snapshots_service()<br>
snaps = snaps_service.list()<br>
snap = [s for s in snaps where
s.description == 'My snap'][0]<br>
</blockquote>
sounds good, thank so much for taking time to
explain, but for the last<br>
entry, I get ;<br>
<br>
snap = [s for s in snaps where s.description ==
'My snapshot2'][0]<br>
^<br>
SyntaxError: invalid syntax<br>
</blockquote>
I apologize, I wrote that too fast. That is SQL
syntax, not Python. In<br>
python should be "if" instead of "where":<br>
<br>
snap = [s for s in snaps if s.description ==
'My snapshot2'][0]<br>

Thank you, it's ok for now.<br>

May I use a version 3 of python?<br>

You SDK supports both Python 2 and Python 3. If
you are using the RPMs<br>
make sure to install the
'python3-ovirt-engine-sdk4' package.<br>
</blockquote>
<br>
python3-ovirt-engine-sdk4 doesn't exist in repos,
only python-ovirt-engine-sdk4<br>
Thanks to your explanations, I begin to understand
the philosophy of this sdk, it's far different from
sdk3.<br>
What's was wrong with the v3, what was the
motivation to write a new version?<br>
Will it be possible to use the old sdk3 (manually
installed) for old scripts in ovirt 4.2 ?<br>

Note that both are supported, but Python 3 doesn't
get a lot of<br>
attention yet, so you may find issues. If you find
any issue with Python<br>
3 let as know, as we are committed to make it
work.<br>
