        I could reproduce a bug: cloning a VDI (fast and slow) from SR-1 to SR-2 does not work.
        I got a pool, current qcow2 (xcp-ng-testing,xcp-ng-candidates), a template (vm), two SR attached via FC HBA, everything else works fine.

          @IgorGlock Thanks for the report. Can you elaborate on the exact steps required to reproduce this? Also, are you running XOA or XO from sources? Which version or commit?

            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 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 🙂
