Re: [ovirt-users] [PySDK v3] Choose storage domain
Juan,
Thank you very much for your help, this is working.
Some comments below.

In order to do that you need to specify that you want to clone the
disks
of the template, and for each disk you need to specify the storage
domain where you want to create it.
This is what I feared, and it was not really obvious at first sight (to
prepare a disks list...).
I think I saw it was less weird in V4.
[...]
Also, please be careful when specifying the cluster and the
template.
You are currently doing this:
cluster=vm_cluster,
template=vm_template,
Not sure how you are assigning the values to those 'vm_cluster' and
'vm_template' variables, but you are probably doing this:
vm_cluster = api.vms.get(name='mycluster')
vm_template = api.vms.get(name='mytemplate')
Here is what I was doing (please don't laugh) :
c_list = api.clusters.list()
# At present (2017), each datacenter contains only one cluster
vm_cluster = c_list[0]
vm_template = api.templates.get(name=template_name)
That combination isn't ideal, because you will be sending with
the 'add'
request the complete representation of the cluster and the template,
when the server only needs the id or the name. Consider doing this instead:
cluster=params.Cluster(
id=vm_cluster.get_id()
),
template=params.Cluster(
id=vm_template.get_id()
),
Is it right to say that this last method is only valid in the api
context, and would not work outside of the api object scope?
I mean : if I want to use your method, I can no longer separate the
preparation of a vm_params object before calling the vms.add, right?
OK, just one second before sending this e-mail, I made a quick test with
the template object and it is working anyway.
Does it mean nothing is instantiated before the api.vms.add call?
