      Hi,

      Nothing useful. Maybe you can try to delete the VMs and redeploy the cluster.

        Ok I will do that. Whilst I redeploy the cluster, what I am looking for? What log to monitor etc?

          I'd say any error in the console during the cloud-init installation.

            @GabrielG I deleted the VMs and redeployed it with3 nodes.
            So far only the Master VM has been created and nothing else. I am missing the 3x nodes.
            When I look at the console of the master VM, all I get is this:

            e59f3920-dbb2-473f-b5c2-ba793197a7b4-image.png

            So the master VM is created but nothing has been deployed

            I have no error on Xen Orchestra screen or log

              The cloud-init installation comes after the step on your screenshot.

              Are the 3 nodes VMs started? Can you post the output of sudo cat /var/log/messages?

                No node come up. Do you need the message log from all the hosts ?

                    @GabrielG I just cleared allthe /var/log/messages logs from hosts and Xen Orchestra and started again:

                    bfbe92db-d559-477d-8b8c-c3fdd1604e71-image.png

                    Host3: /var/log/messages is empty
                    Host4: /var/log/messages is empty
                    XOA: /var/log/messages has the following message repeated 100's time:

                    As before, the master VM is created but nothing more

                    No nodes are created and the recipes page just have a spinning wheel with no error message

                    I hope this is enough information to debug the issue

                      Your first Debian VM isn't booting at all. Are you sure your host is working and supporting HVM guest?

                      Can you boot the Debian 11 template from the XO Hub?

                        Yes, the hosts has other VM running on them. Also on my original post, the master was created and also the nodes. They simply couldn't see each other

                        Yes, I can deploy Debian 11 from the XO Hub but it it won't stay up. The Vm does start and get stuck at the boot process

                        I removed the template and re-installed it again. This time i successfully managed to deploy Debian 11 from XO Hub.
                        I then tried the Kubernetes recipe again and this time the master is created but is not powering on. Should I manually start the VM?

                            Okay so your problem isn't k8s recipe related, but elsewhere (probably the storage).

                              Issue seem to be with the XOSTOR SR. Any chance @ronan-a could test if the K8S recipe work on his XOSTOR SR? I just want to know if it is specific to my setup or XOSTOR in general (bug)

                                I think it's totally unrelated. If you have issues to create the XO Hub Debian 11 VM, nothing else could work after that.

                                  What do you mean? I can create XO Hub Debian 11 on XOSTOR with no issue. I am not sure I understand you ?

                                    What I mean is the fact that the issue with your k8s recipe is not related to the recipe itself, but a problem on your own XOSTOR cluster.

                                      How can we be sure its not a bug and only and issue with my system? This is way i was asking if anyone else running XOSTOR could try to confirm the issue is with my system

                                        Because we identified some issues on XOSTOR recently, and that's exactly what causing your issue. If the VM doesn't boot, there's 0 chance the k8s recipe can work.

                                          @olivierlambert ok so is it a matter to create K8S on local storage and moved them manually to XOSTOR untill XOSTOR issue get a fix?

                                            I would advise to not combine problems, XOSTOR is not completely bug free yet, so if you have an issue to report, get rid of XOSTOR in the equation first.
