      I want to move my VM from server A to B by using continuous replication. Servers are identical. I choose CR because I will have the latest copy available to create the new VM (it is a zimbra mail server so 5 minute down time is important, BTW thank you so much for XO team for giving this feature free for us)

      I did a CR backup of a VM from A server to B server. After successfully replicating, On the B server when I hit the copy VM to the same SR of B, it stuck at 0% and never continues.
      **How should I diagnose this problem. **

      Server has 4 times more storage than the VM.

        Copy can takes time, but staying at 0% isn't normal. Do you have a replication that might interfere while your are doing the copy operation?

            Okay feel free to try with xe vm-copy command directly on the host, maybe we'll have more chance to know what's going on.

              sure.
              just executed
              xe vm-copy new-name-label=newVM vm=copiedVM
              no messages/output yet, will leave it and check back.

                  Can you create a VM or a disk in this SR? Anything in SMlog?

                    @olivierlambert Yes I have 1 running VM (created by this server).

                    I tried many ways still stuck at 0%.
                    I will try to copy VDIs indivudally and crate a new VM. Or should I create a new VM and use existing VDIs?

                    by the way fast clone works. instantly I have a clone up and running.

                      In order to CR to continue after "booting it", you must use a copy.

                      In case of you lost your origin VM, then it doesn't matter if you boot the replicated VM directly.

                      I don't know why full clone doesn't work on this SR.

                        I give up for now 😉
                        I have no idea why it did not work. No error messages on the logs also. It just stuck. anyways thank you @olivierlambert for your time.

                        I created a new VM and attach the copied VDI 1 to it. The second VDI cannot be attached so I delete it and will copy from the source server. Looks like it is working.

                        I have one more VM to process and this time I will double check the steps and share any progress here.
