      @Gheppy it's always easier to fix when we can build a minimal setup that reproduce the issue
      thanks for your report

        Hello, the problem has reappeared.
        This time with a different behavior.
        It hangs at this stage, and the export tasks do not even start/show.

        Info:

        XCP-ng 8.3 up to date,
        XOCE commit fcefaaea85651c3c0bb40bfba8199dd4e963211c

              @Gheppy It's not clear to me. Is it fixed on latest commit on master as of now?

                I update to last commit, two more change is on git now

                d1aff2fd-b61f-45fa-a375-6155ee9bfc60-image.png

                The problem still exists. From what I've noticed, export tasks start being created and then disappear shortly after. And then a few moments later the import tasks appear and it remains blocked like this.

                42647e87-a3ae-451c-9001-555b3ad26bf8-image.png

                Only up to this commit 7994fc52c31821c2ad482471319551ee00dc1472 (inclusive) , everything is ok.

                EDIT: I read on the forum about similar problems. I don't have NBD enabled.

                    I will update to the latest version and look at the logs.
                    Now I have version 7994fc52c31821c2ad482471319551ee00dc1472

                      @Gheppy if this is what I think it should have been fixed by https://github.com/vatesfr/xen-orchestra/commit/3c8efb4dc3e1cb3955521063047227849cfb6ed3

                            hmm,
                            I found the solution, after I read here on forum.
                            I enable this options and save and then disable and save and now is ok. Task is running again. It is running with last commit to
                            So the problem is with these settings which may not exist in the task created before the update.
