        @AllooTikeeChaat yum considers that your medata are recent enough. Ask it to clean them: yum clean all.

          @stormi yum clean all worked. Installed aok and modprobe zfs doesn't complain so that's all good.

          A repair of the ZFS SR fails with the same error and "zpool status: no pools available" and "zfs list no datasets available".

          I'll open a new post if I can't get it working rather than replying to this one.

          Update: fixed the issue ..

              (1) Missing the ZFS packages from the base install.
              (2) Needed a "yum clean all" to be able to install zfs packages.
              (3) Needed to manually import the ZFS zpool

              I'm a noob with zfs so had to work out how to import an existing zpool and once thats done it can be repaired/mounted.

                Good 🙂 So now you are on ZoL 0.8, no need to disable sync anymore 🙂

                  I'm assuming that sync is enabled by default ?

                    Yup, but before (0.8) it wasn't good for performances, at all, due to cache poisoning (no O_DIRECT support).

                      Any chance to get a newer lsblk that supports json output?
                      Would be great for plugins and would make parsing output much easier.

                      Currently installed on XCP-ng 8 beta: util-linux-2.23.2-52.el7_5.1.x86_64

                      (something later than v2.27?)

                      ... ah forget it, I see, CentOS is using the old versions since long time ...

                        Yeah the chances that we'd change the version of such a low level package just for added functionality are very low.

                          @stormi yes and I totally understand that ... I just thought at first, it is so old, there must be something new if CentOS 7.5 is new ... but no 😕

                            hi

                            Is this possible to install xcp-ng in xcp-ng just for tests?

                              Sure you need to enable Nested Virtualization when you create your VM and that's it.

                                  Just updated my homelab server from XCP-ng 7.6 to XCP-ng 8.0 Beta, so far so good. I also tested the new experimental UEFI mode with Windows VM, seems good too.

                                  I also tested the new XOA deployment through the Web interface of my host, perfect !

                                  We will see during the following week how it goes 😉

                                    It does NOT work to migrate a paravirtualized (PV) CentOS6 machine or a PVHVM CentOS7 between two "servers" with Core i3-3110M CPUs in 8.0beta.
                                    C6 throws a "xenopsd, error from emu-manager: Invalid argument" and C7 "xenopsd, error from emu-manager: xenguest Invalid argument".

                                    It works on the exact same hardware in 7.6 so that seems to be a new "unsupported old CPU" limitation, unless it's a proper bug in 8.0b.

                                    I can migrate a Fedora28 (HVM) on that hardware in 8.0b so it appears to depend on what virtualization method the machine uses.

                                      @peder Thanks for testing. It confirms our recent findings related to PV guests indeed! We're working on it and will post here once it's fixed.

                                          @peder Fixed! This fix will be available (as soon as possible) in a future xcp-emu-manager package.
