      I do not understand how the wrong templates can be used by the recipe.

        Yes it is quite strange.

        This XOA has been in use for some time with a couple of pools added and removed over time, so I may be an edge case here.

          Delete the template, maybe it's a previous version 🙂

            @olivierlambert I deleted all templates from XOA by going to "Hub" > "Templates" and using the trash icon to remove them. However it still appears that it uses debian 9. I could try to remove all templates from the system via the windows xcp-ng client. However it may be of importance to know that i have never used the debian 9 template before. While using this recipe was the first time i saw it.

            I remember trying the k8s recipe about a year ago, maybe that has tainted my setup in some way?

              How do you check it's using Debian 9 template exactly?

                @olivierlambert Under the VM page "Advanced" > "Misc"

                  @mathiashedberg I've just checked the ones I built that started all of this... they are deb 9.

                    Can you provide a screenshot?

                    Also, double checking inside the VM that's debian 9 with a cat /etc/issue. Because the original template doesn't mean anything.

                      @olivierlambert Ahh... it is 10 on the inside. 9 on the wrapper 🙂

                        You can create a Debian 10 VM using a Debian 9 template, it doesn't matter (both are HVM guests, same config).

                        The current VM was probably made while Debian 10 template wasn't there yet.

                          So after some more testing it seems the template mapping is wrong again. My k8s VMs started with 500MB, and when i looked at the bash history, i saw that yet again, the k8s VMs were based on an existing VM running on the system. The ram was set to 500MB because thats what the base VM ram settings were. This is the same issue as earlier on.

                            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 🙂
