[ovirt-users] Maximum domains per data center
Hi to all. Can someone confirm to me the value of max domains per data center on ovirt 4.4 ?

[ovirt-users] export to ova
Hi to all. Hi try to ank another time the same question: in our tests ovirt seems to be able to make only one export to ova at time. also on different hosts and datacenter. Someone can explain to us why?? this is for us a big issue, because we use it in a backup script of more than 50 VMs and counting We also already opened a bug without any useful response: https://bugzilla.redhat.com/show_bug.cgi?id=1855782 Regards, -- -- Shellrent - Il primo hosting italiano Security First *Tommaso De Marchi* /COO - Chief Operating Officer/ Shellrent Srl Via dell'Edilizia, 19 - 36100 Vicenza Tel. 0444321155 | Fax 04441492177 ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/3MUV776V2EMSCNIZWUG7P2TNMLQBPYX4/
[ovirt-users] Re: Error exporting into ova
Hi Gianluca, we have read the massage from Jayme, but we have problem with the INTERNAL ansible playbook. Wen we run an export, ovirt internally run the playbook /usr/share/ovirt-engine/playbooks/ovirt-ova-export.yml but only export at time Il 27/08/2020 11:15, Gianluca Cecchi ha scritto: On Tue, Aug 25, 2020 at 3:29 PM Tommaso - Shellrent mailto:tomm...@shellrent.com>> wrote: Hi Gianluca.

Have you got any hint? Regards, Tommaso. My post was one year old. In the meantime you can check these two posts in archives by Jayme (I cc him): https://lists.ovirt.org/archives/list/users@ovirt.org/thread/U65CV5A6WC6SCB2R5N66Y7HPXQ3ZQT2H/#FAVZG32TPSX67DTXIHMGIQXUXNG3W3OE and https://lists.ovirt.org/archives/list/users@ovirt.org/message/JNSY6GYNS6LPNUJXERUO2EOG5F3P7B2M/ In the first post it appears that by default the exports were of type fire and forget (that is what you need) and so he included a wait_for task to instead have them sequential. I think you can borrow from his github playbooks and adapt to your needs. Or Jayme, you could apply a general change where you set a variable (eg sequential_flow) that by default is true and then you modify the export_vm.yml playbook in the task - name: "Wait for export" with the wait condition becoming of kind when: (export_result is not failed) or (sequential_flow|bool == False) This way by default the play workflow remains unchanged, but a user can set sequential_flow to False What do you think about it?

It reads from iscsi multipath (2 paths) with 2x3MB/s and it writes on nfs If I run a dd command from iscsi device mapper device to an nfs file I have 140MB/s rate that is what expected based on my storage array performances and my network. Not understood why the qemu-img command is so slow The question still applies in case I have to do an appliance from a VM with a very big disk, where the copy could potentially have an elapsed of more that 30 minutes... Gianluca I confirm that setting ANSIBLE_PLAYBOOK_EXEC_DEFAULT_TIMEOUT was the solution.

The same operation on vSphere have an elapsed of 5 minutes. What is the eta for 4.3.5?

Hi. No, we use a simple python script that trigger one single export. We have a lot of single server datacenters with local storage, and in all of them we run this scrip almost simultaneously.
