      Yum update is a big help! No need to re-install whole OS 🙂

        Yup, tested that and I only spent 1 minute to do the upgrade from 7.5. I had longer reboot time 😅

            Yay, looking forward to setting up a mirror.

            There seems to be a live migration bug. It happens both with storage migration and between hosts. The VMs migrate to 95% and then it just sits there with network traffic but nothing happening. I also saw this on 7.5 and was hoping 7.6 fixed it.
            Does it have to do with the work around for the now closed source citrix packages?

                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.

                              @rizaemet-0 said in XCP-ng 7.6 RC1 available:

                              migrate issue with Linux or Windows, PV driver installed or not, vm or storage

                              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 🙂
