      Are you sure you removed the templates?

        So this new VM for k8s seems to be based on an existing VM, which itself is based on the Debian 10 template (when it was created a long time ago)

            Our recipe is based on Debian available in XO Hub template.

              In XO, you can search it in Templates view and remove it 🙂

                @olivierlambert Yes i removed it from the Hub > Templates view. It should be noted that i take regular backups of the VMs created with this debian 10 template, so i think it is using them

                Backups are done with the XCP-NG center: 'Pool' > 'VM Snapshot Schedule' setting

                  Please do NOT use XCP-ng Center "snapshot schedule" feature please 😞

                    @olivierlambert For a homelab setup this is currently the only "free" solution to snapshotting that i know of (other than file system based like ZFS).

                    Going from "free" to 77USD a month is quite a jump imo.

                      It's a bit off topic but:

                      1. Remember, snapshot is not backup
                      2. You can use XO from the sources to have all XO source code without feature restrictions (but XO hub/recipe is XOA because it's a service connected on xen-orchestra.com where we host the machines).

                      Anyway, let's try to find the original problem 🙂

                        Xen Orchestra is free and open source. You can follow the build from source instructions or use a script like the one posted to my github

                          The snapshot functionality is still quite tempting to use, as I have not had any issues with it before now. I'll admit I'm not too up to date on what features are recommended or not when it comes to XCP-NG.

                          @DustinB I think its great that we have such useful software that is free and open source. If my comment came off as negative I apologize, that was not my intention.

                          Moving forward I would assume that removing all my snapshots would remedy the issue. However I'm not too sure on how keen I am on doing that right at this moment with my current setup, maybe on a different test lab.

                            @mathiashedberg the snaphots might be indeed the problem.

                            When looking for the template, the recipe looks for a VM with xo:resource:xva:id=<template uuid> in its other-config, a snapshot of the template VM would probably have this field se and it should not.

                            Can you check if it's the case? and if the is-template field is true.

                              That's an interesting thing. I think it might be a potential bug because of XenCenter snapshot algorithm that handle is-template differently than XO.

                                @olivierlambert should I also check that is-a-snapshot is false?

                                  Double check what do you have when we install a template from XO Hub. If is-a-snapshot is at false, then yes, add this condition. We should use the installed template, not anything else.

                                      So you are correct on all those points. Here are the relevant params from the snapshot that was being used:

                                      is-a-template ( RW): true
                                      is-a-snapshot ( RO): true
                                      other-config (MRW): auto_poweron: false; xo:resource:xva:id: a677aa91-f5d5-46ec-bd53-956b73fc7871; xo:resource:namespace: Debian10; xo:resource:xva:version: 1.0.0; import_task: OpaqueRef:71bd99c2-11c3-4306-a5b9-7fe6e86f551b; mac_seed: 02166646-6e3b-de07-1b11-872d538d3f01; base_template_name: Debian Stretch 9.0; install-methods: cdrom,nfs,http,ftp; linux_template: true

                                        @mathiashedberg good to know.

                                        So you can wait for the fix or remove the xo:resource:xva:id from the other_configs of the snapshots or remove the snapshots

                                          @benjireis Looks like version 5.56.0 runs as expected! No issues so far!
