      New updates are available for those who have installed the beta, the RC or from the pre-final ISOs. They fix an issue that no one had seen yet but very important: the chronyd service was not enabled when updating via yum, nor chrony-wait.service, vm.slice and sm-mpath-root.service (Citrix Hypervisor's update from 8.0 to 8.1 exhibits the same issue).

      They also modify the tty console welcome message to mention Xen Orchestra as the official graphical client.

      I have also built new ISOs ("prefinal2") with the updated packages. I hope those will be the final ones. Download from https://updates.xcp-ng.org/isos/8.1/

        @Biggen It's on my TODO list to write detailed instructions for that migration before the release. I'll follow the procedure myself and see what happens. Others can comment too and help making it perfect.

        Done: https://github.com/xcp-ng/xcp/wiki/XCP-ng-8.1-Release-Notes#migrate-from-experimental-ext4-storage-repositories

          Can you export and import VMs with xcp-ng Center? I have a single host pool so I'm not sure what the best method is of exporting them and then importing them once the new SR is created.

          My XO Community Edition resides on the experimental SR . So I can use that to move/export my other VMs first but I'm not sure how to move the actual XO CE last. I may have to simply reinstall it from scratch which isn't a big deal.

            @Biggen Not sure if this will work for you, but I temporarily migrated my VDIs to my backup source (I created an NFS SR) and then deleted / recreated my local storage.

              I think that is what I'll do.

              Its the import that I'm not quite sure how to handle. If I backup everything to a NFS and delete the old SR, then I have no controlling XO any longer to begin the import. So I either have to manually reinstall XO CE or use xcp-ng Center.

                @Biggen To be clear, I didn't export / import. Here's what I did --

                • Created a new NFS SR on my backup device
                • Migrated the existing VDIs to the NFS SR
                • Removed the existing local storage (was LVM)
                • Recreated the local storage as Ext4
                • Migrated the disks back to local storage

                IIRC, I had to restart a few of the VMs post migration but otherwise the process worked fine for me

                  What did you use to migrate with? Did you have another host where you could run XO(A) from?

                    @Biggen No, the host doesn't change at all. You are just moving all disks to different storage so that you can recreate your local storage. I believe the latest version of XO lets you do this from the SR > Disks tab.

                    If you run into issues with moving your XO instance, you could always spin up a 2nd instance or use XOA.

                      Oh, I see. You are talking about migrating everything including XOA to NFS and running it from there while I'm destroying/recreating the SR, and then moving everything back.

                      Yeah I get it now.

                        Upgrading to 8.1 from 8.0 went just fine. Thanks for the help @Danp. Moving everything to a temporary NFS share worked easy (although one stubborn VM couldn't be migrated for some reason. I had to perform a copy instead).

                        Just be aware if you pass through any disks or have a local ISO SR setup in dom0, you will have to set it back up again. The pass through disks are easy since the data itself on the drives isn't touched. You just have to pass them back through and reattach to the appropriate VM. The local ISO SR is another story since it gets wiped if it resides in dom0. Not a big deal. Just have to copy back into it the installation ISOs required and add it back in the storage menu.

                          Why not just setup an NFS one?

                            @Danp I should but I use it so seldom that I just have never got around to it. Might as well now so I only have to build it again from scratch just this once!

                              Import (in XO and XCP-ng center) / restore from back up is broken. It works with 8.1 RC1 but with latest patches applied or prefinal 3 it fails.

                              Think this is the relevant bit of the log,

                                  @jmccoy555 @Danp what's your XAPI version?

                                    Also which version of XO are using? What kind of backup were you trying to restore?

                                        @jmccoy555 Can we have the full XO log with the name of the action that created the error?
                                        Can we have the XCP-ng log as well corresponding to this error?

                                          I also have exported the VM from XO as a .XVA and tried importing with XO and XCP-ng center, both fail but work with 8.1 RC1 before patches.
