      I got XOA appliance with trial license for our lab.
      Release channels: latest
      Current version: 6.4.0

      I removed the 2 SR and created them new, use qcow2 again. VM migration from SR-1 to SR-2 failed too.

        @stormi installed updates. Did some backups and VM migrations between various storages (bad and qcow2) looks good so far.

          @IgorGlock Are you able to open the support tunnel for us to investigate? You can either post the tunnel ID here or open a support ticket.

            @IgorGlock Hello,

            Could you share the exception that should be in /var/log/SMlog?

              Hello,

              I deleted the entire XOA and downloaded fresh image, recreated configuration and blank SR.
              The issue is gone. I will test some VDI migrations this week.

              There are is some performance impact and timeouts when creating 100-200 VMs on single 10 TB SR. I use xo-cli vm.create script. See you later 🙂

                    So in consequence the update seems to simply fail. I am aware that the manually installed zabbix packages are not "official" packages. However, from my current understanding the error looks more like a non-zabbix related issue. I am wondering, since I have another exactly identical server, which updated fine. If you need some informations, just let me know.

                      Sorry, about this. I think when migrating PV VMs from a previous system I had issues and "needed" to install "qemu-img" and I did not remember. So removing it, solved the problem. So all my fault. Sorry about this message!!!

                        Ran the 2 updates released today and...
                        Back to only showing one VM in Backup/Restore as it did a month or 2 ago.
                        Ran the replication job and all VMs showed up in Backup/Restore again. (XO5)
