Re: [ovirt-devel] REST api and template creation

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: POST /api/templates HTTP/1.1 Host: ovirt.dkmon.com Accept-Encoding: identity Content-Length: 2656 Filter: False cookie: JSESSIONID=2Ihu3uUWFhvl2xbsi5i7yBip.undefined Prefer: persistent-auth Content-type: application/xml Accept: application/xml <template> <name>UDSP_ovirt-21</name> <description>UDS pub for ovirt at 2015-05-09 08:27:06</description> <vm id="3774dcd0-9e1a-47af-9560-fde85f46bfa1"> <disks> <disk href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1/disks/f96b3718-3ccf-42f4-8537-e20dc5dd7bc3" id="f96b3718-3ccf-42f4-8537-e20dc5dd7bc3"> <actions> <link href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1/disks/f96b3718-3ccf-42f4-8537-e20dc5dd7bc3/deactivate" rel="deactivate"/> <link href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1/disks/f96b3718-3ccf-42f4-8537-e20dc5dd7bc3/activate" rel="activate"/> <link href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1/disks/f96b3718-3ccf-42f4-8537-e20dc5dd7bc3/export" rel="export"/> <link href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1/disks/f96b3718-3ccf-42f4-8537-e20dc5dd7bc3/move" rel="move"/> </actions> <name>no-os_Dsk1</name> <description>Small empty disk</description> <link href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1/disks/f96b3718-3ccf-42f4-8537-e20dc5dd7bc3/permissions" rel="permissions"/> <link href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1/disks/f96b3718-3ccf-42f4-8537-e20dc5dd7bc3/statistics" rel="statistics"/> <vm href="/api/vms/3774dcd0-9e1a-47af-9560-fde85f46bfa1" id="3774dcd0-9e1a-47af-9560-fde85f46bfa1"/> <alias>no-os_Dsk1</alias> <image_id>a79f7fe7-bcae-4cc3-8b11-d60702a46147</image_id> <storage_domains> <storage_domain id="a893809b-2ba9-4910-a7f3-9bfdde2efbb8"/> </storage_domains> <size>1073741824</size> <provisioned_size>1073741824</provisioned_size> <actual_size>0</actual_size> <status> <state>ok</state> </status> <interface>virtio</interface> <format>raw</format> <sparse>true</sparse> <bootable>true</bootable> <shareable>false</shareable> <wipe_after_delete>false</wipe_after_delete> <propagate_errors>false</propagate_errors> <active>true</active> <read_only>false</read_only> <disk_profile href="/api/diskprofiles/40def02e-3802-4122-a768-cb6b9518896e" id="40def02e-3802-4122-a768-cb6b9518896e"/> </disk> </disks> </vm> <cluster id="00000001-0001-0001-0001-00000000019d"/> </template> reply: 'HTTP/1.1 400 Bad Request\r\n' header: Date: Sat, 09 May 2015 06:27:13 GMT header: Server: Apache/2.4.6 (CentOS) OpenSSL/1.0.1e-fips header: JSESSIONID: 2Ihu3uUWFhvl2xbsi5i7yBip.undefined header: Content-Type: application/xml header: Content-Length: 180 header: Connection: close 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
