      The update for 7.6 has been made available as a regular update, as xcp-emu-manager-0.0.6-2.x86_64.rpm. It should prevent most migration crashes, but can still get stuck when the VM is heavily loaded. Instead of failing directly, it will now try to wait for a low enough activity to resume the process. We're still working on it to bring a better, complete solution.

          An update to XCP-ng 7.6 has been pushed: xcp-emu-manager-0.0.9-1, that fixes all known migration issues (well, except this bug from XenServer: https://github.com/xcp-ng/xcp/issues/111). Update for XCP-ng 7.5 is being prepared.

          oallart created this issue in xcp-ng/xcp

          closed Live migrating HVM linux (and others?) with storage migration from any older release to 7.6 works but vm dead #111

              New update candidate for XCP-ng 7.6. It adds support for NFS 4.1, that has been contributed by a member of the community and already merged upstream in the XAPI project!

              Install it:
              yum update sm sm-rawhba --enablerepo='xcp-ng-updates_testing'

              Revert:
              yum downgrade sm sm-rawhba

              Thanks in advance for your feeback!

                          So did anyone install the update candidate for sm, check that they see no obvious regression and ideally test NFS 4.1 support?

                              @stormi I did not test it (yet) .. currently copying loads of vm data around at work... but if all goes well I have a free storage next week that will become our new nfs4.1 server for work ... stay tuned πŸ˜•

                                @rizaemet-0 here is a XCP-ng Center with NFS 4.1 support: https://github.com/xcp-ng/xenadmin/releases/tag/v7.6.3.21

                                Just add your NFS SR via the normal assistant, the NFS 4.1 option is right there.

                                  I create a nfs sr with nfs 4.1 with xcp-ng center v7.6.3.21. success.
                                  live storage migrate a vm to this sr. success.
                                  live vm migrate to another host. success.
                                  backup vm with xo. success.
                                  I tested copy-paste file in itself and nfs4, nfs4.1, fc between each other. nfs 4.1 speed is like nfs4 speed for my environment.
                                  heavy i/o for 24 hours. no any performance or another issue.

                                    Do you have better perfs than 4.0 by the way?

                                      @olivierlambert Similar performance for my environment. I did not any specific test. Just copy-paste files.
                                      By the way, is multipath connection (or pnfs) possible xcp-ng between storage with nfs4.1?

                                        It should be possible if you SR is supporting pNFS (because IIRC, it's included in 4.1 protocol).

                                        However, pNFS doesn't remove the usual SPOF (metadata NFS server)

                                          pNFS may not be available in XCP-NG's kernel. I see option CONFIG_NFSD_PNFS unset where as most of the distros have CONFIG_NFSD_PNFS=y

                                            @r1 I think that config option is to enable pNFS server support, not the client. I'm pretty sure this being disabled just means that XCP-ng can't be used as a pNFS server (though a VM running on it certainly could).
