This look like this bug, fixed in version 4.1 of the SDK:

  Importing a VM using the SDK fails
  https://bugzilla.redhat.com/1408839

However there is a good practice that I recommend you to apply, which
will probably avoid the issue. That good practice is avoid sending to
the server the complete objects that you got from other requests. For
example, in this case you are sending to the server the complethe 'tpl'
and 'c' clusters that you got from other requests. Instead of that, try
to send only what is required:

  pool = ovirttsdk4.types.VmPool(
name='PRUEBA',
size=1,
type=ovirtsdk4.types.VmPoolType.MANUAL,
template=ovirtsdk4.types.Template(id=tpl.id),
cluster=ovirtsdk4.types.Cluster(id=c.id)
  )
  vm_pools_servcie.add(pool=pool)

The key point here is creating new 'Template' and 'Cluster' objects that
only contain the 'id', as that is all what the server needs. If you send
the complete template and cluster you are wasting resources, and
exposing yourself to bugs like the mentioned above.

Please try that and let us know if it solves your issue.

[ovirt-users] Getting error while trying to add VmPool using ovirtsdk4 version of the python api

2017-02-10 Thread Manuel Luis Aznar 
Hello there,

I am trying to add a VmPool to oVirt using the python ovirtSDK4 with
following lines:

I am omitting the import packages lines and connection lines.



system_service = connection.system_service()

vm_pools_service = system_service.vm_pools_service()

templates_service = system_service.templates_service()

clusters_service = system_service.clusters_service()

tplist = templates_service.list(search='name=prueba')

tpl=None
biggest=-1
for t in tplist:
 ver = t.version
 if ver.version_number > biggest:
 biggest = ver.version_number
 tid = t.id
 tpl = t

c = None
for cluster in clusters_service.list():
if cluster.name == 'Pruebacluster':
c = cluster

pool = ovirtsdk4.types.VmPool(name='PRUEBA',size=1,type
=ovirtsdk4.types.VmPoolType('manual'),template=tpl,cluster=c)
vm_pools_service.add(pool=pool)



I am getting the following error:

   Fault reason is "Request syntactically incorrect.". Fault detail is "For
correct usage, see:
https://ovirt.example.com/ovirt-engine/api/v4/model#services/vm-pools/methods/add;.
HTTP  response code is 400.

I am a newbie in using this version of the API, suppose this is quite easy
problem.

Thanks for all the answers to come,
Manuel
