Hi. If it's any help to you we use packer to create qemu image (in qcow2 format) and then ansible to generate template on ovirt cluster. For template we used this project: https://github.com/jclaret/packer-templates With kind regards, Pavel On 22/06/2023 08:52, Arik Hadas wrote:

Hi,

I use a set of templates, generated in one cluster and re-used in multiple clusters. The clusters do not have direct connections between each other. My dev environment can talk to all the clusters. Currently,

1. I export the templates (as OVAs) to one of the nodes (example: node1.source.cluster), from the ovirt console (https://management.source.cluster) 2. scp the templates to my dev machine (example: scp -r node1.source.cluster:/tmp/ovirt_templates /tmp/ovirt_templates) 3. scp the templates from my dev environment to the target cluster (example: scp /tmp/ovirt_templates node1.target.cluster:/tmp) 4. Import the templates using the ovirt console of the target cluster (https://management.target.cluster)

This is highly a manual job and I am trying to automate the process using ansible. I am unable to work it out using the ovit_template module documentation (https://docs.ansible.com/ansible/latest/collections/ovirt/ovirt/ovirt_templa...) and could not able to see any other module in this relation.

Has anybody done this before and point me to the right direction? Or if there is a better process than what I follow above, please suggest me one.

you didn't elaborate on what doesn't work for you using Ansible, I suppose the ability to export a template as an OVA is missing, right? in that case, the following process could work: 1. provision a VM from the template (it can be thin-provisioned vm to save time) 2. export the VM to an OVA 3. remove the VM 4. import the OVA as a template (see "Import external ova template" in the documentation of ovirt_template_module)

it should be possible to import an OVA of a VM as a template from the CLI/Ansible

in addition, if you look for ways to improve the flow you described above, I'd suggest to use shared storage in order to save you from copying the OVA (e.g., configure an NFS share that is mounted to hosts on both environments - export to that NFS share on the source environment and import from that NFS share on the target environment once the export operation completes)

Please let me know if you need more information in this regard.

Hi Pavel, Did you use also terraform to start the vms? Thanks, Marcello

Thanks for taking time for responding, @arik.

"you didn't elaborate on what doesn't work for you using Ansible" - I have no issues creating a template using ansible. I have not raised an ansible issue in particular.

"I suppose the ability to export a template as an OVA is missing, right?" - Not exactly.

My requirement is to make a template available from one ovirt cluster to another ovirt cluster that are not connected. I have elaborated how I am doing it currently (which is highly manual).

" export the VM to an OVA" - I do this using the ovirt_termplate ansible module. However, you can do this only to a hosted storage within the cluster.

"4. import the OVA as a template (see "Import external ova template" in the documentation of ovirt_template_module)" - I have been using the 'ovirt_template' ansible module for the past couple of months. I have not figured out how I could import an OVA template from a node. For example, if I manage to copy the template to one of the cluster nodes (say, node2.my.ovirt.cluster:/tmp/ova_template/my_template.ova), I could not work out hos to import this OVA into my cluster. Do you have some sample code, if this is easy enough?

ah you're having an issue with importing the produced OVA as a template on the target environment,ok did you try to run the code snippet from the documentation of the ovirt_template module: - name: Import external ova template ovirt.ovirt.ovirt_template: cluster: <target cluster> name: <new name> state: present timeout: 1800 poll_interval: 30 kvm: host: <host on the target environment> url: ova:///tmp/test.ova storage_domain: <target storage domain> ?

Thanks

@Arik the import worked are expected. I tried to do the reverse - exporting a template to a node as an OVA template. But could not get it working. Here is what I have tried: ``` - name: Export the template ovirt.ovirt.ovirt_template: auth: "{{ovirt_auth}}" cluster: "{{source_cluster_name}}" name: "{{source_template_name}}" state: exported export_domain: "hosted_storage" timeout: 1800 poll_interval: 30 kvm: host: "{{export_node_name}}" url: "ova:///tmp/{{source_template_name}}.ova" storage_domain: "hosted_storage" ``` Upon execution of the above, nothing happens (the script completes instantly with no error) and following is the ansible output: ``` TASK [Export the template] **************************************************************************************************************** ok: [localhost] ``` The OVA is not copied to the local disk of the 'export_node'. Can you please suggest what I am doing wrong or come up with the right task? I could not find any example for the 'exported' state of the ovirt_template. Thanks
