        So I read about the 'VM snapshot with disk exclusion' feature.

        Is this supported at the XAPI level now? If so, how would one go about using it?

        Regards

          @Fungusware Hi!

          Yes this feature is supported at XAPI level, the VM.snapshot method now has a ignore_vdis field which is a list of VDI ref to not include in the snapshot.
          This also available through xe:

          xe vm-snapshot vm=... ignore-vdi-uuids=uuid1,uuid2...
          

          Regards

            @Fungusware Yes, @BenjiReis spent some time to make that contribution to XAPI upstream, see https://github.com/xapi-project/xen-api/pull/4563

            benjamreis opened this pull request in xapi-project/xen-api

            closed Add `ignore_vdis` to `VM.snapshot` method #4563

              Note: this is already implemented in Xen Orchestra since a while πŸ™‚ (by default we try to ignore the [NOBAK] disk if XAPI is able to do it, which is now the case for 8.3)

                @BenjiReis Thanks for the info.

                I'll see if I can support into the SDK also, at least for .NET anyway.

                      @olivierlambert Yes, I had been doing this also for quite some time. It was certainly one of the most requested features. It also felt a bit 'brute force' to me so would be nice to use it built in.

                        @olivierlambert Well.. I have been doing the occasional "yum update" with no new problems. Everything is working great, but I still have that re-scanning of the FS every 30 seconds.. Not impacting anything but just a little weird...

                          What is current status? What is the rough expectation of next alpha/beta release

                          The next planned release should be the first beta. There's no precise ETA yet, but first quarter of 2023 is a likely window.

                          Applying updates regularly on top of the alpha will also give you the same end-result.

                          There are a lot of updated packages that are being prepared. They're currently in the xcp-ng-testing yum repository, because we haven't had time to test them all in our internal CI. All I could assess is that they install well (yum update --enablerepo=xcp-ng-testing) and that the server I installed them to rebooted without any visible issue. Once tested, early January, they'll be moved to the xcp-ng-base repository and offered as updates to anyone running yum update on their 8.3. If you want to give it a go ahead of time, you can install them and see if everything works well or not, so that we can quickly work on any issues early January.

                          Recent work on 8.3 touched:

                          • the installer (soft RAID support improvements, IPv6 support, contribution of various small improvements to upstream repositories...)
                          • automated installation ISO generation
                          • adding memtest86+ to the installer, both in BIOS and UEFI modes
                          • upgrading all packages to the same level as Xenserver 8 Stream's (that's the new name for Citrix Hypervisor 8 Cloud) preview update channels - we had 4 months of changes to catch up with.
                          • redirecting http://ip_or_name_of_xcpng_server/ to https://ip_or_name_of_xcpng_server/
                          • ongoing work with XenServer on the python2 to python3 transition
                          • work on UEFI certificate handling, to reach a stage where it answers both XenServer's and our needs
                          • and more.

                            Hello,
                            I have some trouble with update from 8.2 to 8.3

                            I boot the installation from USB with Image xcp-ng-8.3.0-alpha2.
                            Everything works until I get to the installation. The backup of the old version is still made, then this error message appears:
                            Old partition layout is unsupported, run prepare_host_upgrade and try again. Reboot
                            The 8.2 installation is a 3 month old fresh installation, I doubt there is an old partition type in this 8.2 version.
                            I removed all disks except the boot disk which only contains the XCP-NG system. Still the same error.
                            The partition structure of the disk is as follows:

                            Model: ATA TS512GSSD720 (scsi)
                            Disk /dev/sda: 512GB
                            Sector size (logical/physical): 512B/512B
                            Partition Table: gpt
                            Disk Flags: pmbr_boot

                            Number Start End Size File system Name Flags
                            4 1049kB 538MB 537MB bios_grub, legacy_boot
                            1 538MB 4295MB 3757MB ext3
                            2 4296MB 8590MB 4294MB ext3
                            3 8591MB 512GB 504GB lvm

                            Does anyone have an idea what's going wrong.

                            I don't want to do a fresh installation because then I have to restore a lot of data. It's my test machine and I have a backup, but with 29 TB it takes days to restore and without data there is little point in testing 8.3.

                            regards Joerg

                                  πŸ€” This is the old partition scheme πŸ€”

                                  It can't be a fresh install, it's not possible.

                                  edit: ah wait. Can you do a mount command?

                                  edit 2: a basic lsblk should display where the partition is mounted, did you copy/pasted everything?

                                    I'am shure that it is a new installation from 3 month ago, it is a new Server and I bought it 3 month ago.

                                        You should have 2x 18G partitions (/ and a backup one), 1x 4G partition (/var/log) and a 512MB partition (/boot)

                                            Okay so this is the old partition scheme. Can you repeat exactly what did you do with this machine? I mean initially. I don't know how to even get the old partition scheme in the first place with XCP-ng (there's 0 edition of XCP-ng with this old partition scheme, it's only before XenServer 6.5)
