Template creation is failing, because Engine is not receiving the alias 
which apparently is required since 3.5.
This is the XML sent to engine. Alias is there.
API bug?

 Hello 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 
 http://www.ovirt.org/Universidad_de_Sevilla_Case_Study. ).

 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. :(

 The idea is allow to create the template in the storage that the 
 administrator of UDS selects.

 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):

 vm is the origin vm:

             # Create disks description to be created in specified 
 storage domain, one for each disk
             sd = 
 params.StorageDomains(storage_domain=[params.StorageDomain(id=storageId)])

             dsks = []
             for dsk in vm.disks.list():
                 dks.append(params.Disk(id=dsk.get_id(), 
 storage_domains=sd, name='test', alias='test'))

             disks = params.Disks(disk=dsks)

             template = params.Template(
                 name=name,
                 vm=params.VM(id=vm.get_id(), disks=disks),
                 cluster=params.Cluster(id=cluster.get_id()),
                 description=comments
             )

             return api.templates.add(template).get_id()

 This is the debug output of the request:

 The response : Cannot add Template with an empty disk alias

 On server, i got this on ovirt log:

 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

 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... :) )

 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... :(

 Thank you very much

 Adolfo Gómez

      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>
