all,

My name is Adolfo, i'm in charge of developing of UDS (you can see
something about it on ovirt home page, the case study
<a class="moz-txt-link-freetext" href="http://www.ovirt.org/Universidad_de_Sevilla_Case_Study">http://www.ovirt.org/Universidad_de_Sevilla_Case_Study</a>. ).
<br>
<br>
Recently (a couple of days ago), i started to test UDS against
ovirt 3.5, and sudenlty Template creation as was supported
previously does not works. :(
<br>
<br>
The idea is allow to create the template in the storage that the
administrator of UDS selects.
<br>
<br>
The process is simple and was working perfectly before to 3.5
release (on 3.4, 3.3, 3.2 as long as i can remember). After
getting all the data we need, we do the following (code follows):
<br>
<br>
vm is the origin vm:
<br>
<br>
# Create disks description to be created in specified
storage domain, one for each disk
<br>
sd =
params.StorageDomains(storage_domain=[params.StorageDomain(id=storageId)])<br>
<br>
dsks = []
<br>
for dsk in vm.disks.list():
<br>
dks.append(params.Disk(id=dsk.get_id(),
storage_domains=sd, name='test', alias='test'))
<br>
<br>
disks = params.Disks(disk=dsks)
<br>
<br>
template = params.Template(
<br>
name=name,
<br>
vm=params.VM(id=vm.get_id(), disks=disks),
<br>
cluster=params.Cluster(id=cluster.get_id()),
<br>
description=comments
<br>
)
<br>
<br>
return api.templates.add(template).get_id()
<br>
<br>
This is the debug output of the request:

The response : Cannot add Template with an empty disk alias
<br>
<br>
On server, i got this on ovirt log:
<br>
<br>
2015-05-09 08:14:16,940 WARN
[org.ovirt.engine.core.bll.AddVmTemplateCommand]
(ajp--127.0.0.1-8702-8) CanDoAction of action AddVmTemplate failed
for user admin@internal. Reasons:
VAR__ACTION__ADD,VAR__TYPE__VM_TEMPLATE,ACTION_TYPE_FAILED_TEMPLATE_CANNOT_BE_CREATED_WITH_EMPTY_DISK_ALIAS<br>
<br>
After a lot of tests, i have no idea how to resolve this, and if
this is related to the change that was made to admin interface
that alias is required when creating a template (googling have
found something related to that change). The case is that even
sending an "alias" (the alias is unique anyway, but is hardcoded
in the example because of tests... :) )
<br>
<br>
I don't know where to ask for help on this, if this is my own
fault of is something that was missing on ovirt engine. We need to
be able to create machines templates on whatever storage is
decided... :(
<br>
<br>
Thank you very much
<br>
<br>
