        This is migrating from local SR to shared SR(Storagemotion)...
        The VMs CPUs max out/hang when this happens.
        xensource.log while it is hanging constantly repeats the following lines

          Just found this,

          Oct 12 15:23:53 xcp-ng-tnogfalp xenopsd-xc: [debug|xcp-ng-tnogfalp|39 |Async.VM.pool_migrate R:963d85595a12|xenops] looking for emu-manager in 
          

          Should it be calling for the new xcp-emu-manager?

              I also experienced this a few times with XCP-ng 7.5.

              In one case (Windows VM) a process in Windows was on 100%, after I killed that process, the VM spontaniously migrated... till the process killing the VM was very slow, was a pain to get pass the login screen and start the taskmanager.

              So I expected old PV drivers to be the reason. After upgrading the PV Driver (with latest package from Citrix) the issue went away for that VM ... but I did not test this further because it was on a productive pool.

                I've had this happen migrating the XOA VM.
                I also have it happening on some linux VMs that don't have any tools installed.

                  I also experience this migrate issue with Linux or Windows, PV driver installed or not, vm or storage live migrate. Ramdomly as @olivierlambert said. Not always.

                    I just updated the first message to add a note for those who want to update their 7.6 beta to 7.6 RC1.

                      I can reproduce on my end almost every time. the migration hangs more often than not.

                        Anything in logs that could help us to track down the issue?

                          I haven't seen much, but I am curious about my post earlier about xcp-emu-manager, I see emu-manager referenced in the logs and was curious if xcp-emu-manager should be referenced.

                            I did a test. Tried a storage live migrate on a vm which have one sanpshot. And cause this migrate problem. stack in 99%.
                            Then I delete snapshot of this vm and wait coalesce process. then tried again storage live migrate. Successfull.
                            I did this test on same vm. so, for now I think problem source is look like snapshot. I will do more test.

                                  Okay so it's not the right topic indeed, but I really want to know if you still have these issues on 7.6 RC 🙂

                                      Thanks a lot! It's important to test between 2x 7.6 hosts, to be sure it's still an issue and not a problem from another version in the middle 🙂

                                        Mine is between multiple 7.6 hosts. PV tools, no PV tools, linux, windows. It all does it.

                                            No snapshots. It happens on both storage migrate and love migrate.
