I wrote a simple task that is using the ovirt_vm module https://docs.ansible.com/ansible/latest/modules/ovirt_vm_module.html -- it essentially loops over a list of vms and exports them to OVA. The problem I have is the task is deemed changed once it successfully submits the export task to oVirt. This means that if I gave it a list of 100 Vms I believe it would start an export task on all of them. I want to prevent this and have it only export one VM at a time. In order to do this I believe I will need to find a way for the task to wait and somehow verify that the export was completed before submitting a task for the next VM export. Any ideas? - name: Export the VM ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ item }}" state: exported cluster: default export_ova: host: Host0 filename: "{{ item }}" directory: /backup/ with_items: "{{ vms }}" _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/PXYAQ7YEBQC...

That may work since the file will be tmp until finished being written. I was also just looking at the ovirt event info module https://docs.ansible.com/ansible/latest/modules/ovirt_event_info_module.h... -- I was thinking that I might be able to watch the event info wait on the event which shows the export was successful i.e. Vm X was exported successfully as a Virtual Appliance to path.... There is also the event index which could be useful in terms of getting a starting point for the event search. I thought there would be a module or API for the running oVirt task list but so far I haven't been able to find any way to get info on oVirt tasks. I'll see if I can get something working with your suggestion and keep looking at API and ansible modules to see which make sense to use. I'm also worried that timeout issues may occur if I start waiting in some cases an hour or more for very large VM backups to complete before moving on to the next with ansible. Thanks!

Jan, I just ran a quick test with your suggestion and it seems like it is working as intended. I need to do more testing with it but it looks like this may well be a viable solution: --- - hosts: localhost connection: local vars: host: hostX cluster: default directory: '/backup/' ova_ext: ova vms: - ovatest - ovatest2 tasks: - name: Backup VMs include_tasks: backup-test.yml loop: "{{ vms }}" backup-test.yml: --- - name: "Export VM to OVA" ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ item }}" state: exported cluster: "{{ cluster }}" export_ova: host: "{{ host }}" filename: "{{ item }}.{{ ova_ext }}" directory: "{{ directory }}" - name: "Wait for export to finish" wait_for: path: "/backup/vm.ova" # will change to using vars here The backup folder isn't accessible from where I'm running ansible from so I will need to check it remotely but that should be easy to solve.
