      @ronan-a I was in the bad assumptions that all the things that has been installed in this guide where new packages for RunX.

      So when it began to give problems I went for the remove option. My bad!

      Everything popped out from the fact that after that I could make the vms start again updating the packages as soon as I was starting the dockerd I was loosing connectivity in the host.

      So I wanted to remove it.

        Been interested in this since the first blog post but never got round to trying it. Is this still a 'thing'? I'm having little luck trying to get it work and am seeing most of the errors already posted, and have tried the fixes but still no luck. I would guess I may have a template issue.......

        Mainly wondering if its worth some effort or if its best to just run docker in a VM?

        Thanks.

          Hello!

          @ronan-a will guide you if you have problems on making it work πŸ™‚

          There's still some work needed to be a 100% feature complete product, in the meantime, if you want to go in production, go for the VM+container inside πŸ™‚

            @olivierlambert ok, if its still planned to be a feature then I'm up for playing.... testing!!

            @ronan-a is this the best way to get the template? The rest of the instructions look pretty simple to follow so I don't think I've got them wrong..... πŸ˜„

            xe vm-install template=Debian\ Buster\ 10 new-name-label=tempforrunx sr-uuid=7c5212f3-97b2-cdeb-b735-ad26638926e3 --minimal
            this uuid is of the SR created by the step in the first post?

            xe vm-param-set uuid=a2d46568-c9ab-7da2-57cb-d213ee9d8dfa HVM-boot-policy=""
            uuid that is a result of the first step?

            xe vm-param-set uuid=a2d46568-c9ab-7da2-57cb-d213ee9d8dfa PV-args=""
            uuid that is a result of the first step?

            xe vm-param-set VCPUs-max=2 uuid=14d91f2f-a103-da0e-51b3-21c8db307e5d
            what is this uuid?

            xe vm-param-set VCPUs-at-startup=2 uuid=14d91f2f-a103-da0e-51b3-21c8db307e5d
            same again, where does this uuid come from?

            xe vm-disk-remove device=0 uuid=cb5a6d67-07d5-b5ea-358a-7ee0d6e535af
            and this one too?

            xe template-param-set is-a-template=true uuid=a2d46568-c9ab-7da2-57cb-d213ee9d8dfa
            uuid generated by the 1st step

            Thanks.

              Right!

              Regarding all xe vm-param-set/xe vm-disk-remove/xe template-param-set commands, you must use the VM UUID returned by the xe vm-install command. I edited the post regarding that. πŸ˜‰

                @ronan-a thanks (was obviously too late for me to think about trying that!!) but no luck 😞

                Not sure what I'm doing wrong now, or if I need an update??

                When I created the SR I had to give a host-uuid. I obviously used the host that I'm installing on.

                    Please, Please, Please make this document itself with bash variables when it comes to the various UUIDs:

                    [XCP-ngHostX]# SRuuid=$(xe sr-list name-label="Local storage" --minimal)
                    [XCP-ngHostX]# RunXdebTemplateName="My RunX Template based on Deb10"
                    [XCP-ngHostX]# RUNXdebTEMPLATEuuid=$(xe vm-install template="Debian Buster 10" new-name-label="${RunXdebTemplateName}" sr-uuid=${SRuuid} --minimal)
                    [XCP-ngHostX]# echo ${RUNXdebTEMPLATEuuid}
                    [XCP-ngHostX]# xe vm-param-set uuid=${RUNXdebTEMPLATEuuid} HVM-boot-policy=""
                    [XCP-ngHostX]# xe vm-param-set uuid=${RUNXdebTEMPLATEuuid} PV-args=""
                    [XCP-ngHostX]# xe vm-param-set uuid=${RUNXdebTEMPLATEuuid} VCPUs-max=2
                    [XCP-ngHostX]# xe vm-param-set uuid=${RUNXdebTEMPLATEuuid} VCPUs-at-startup=2

                    [XCP-ngHostX]# xe template-param-set is-a-template=true uuid=${RUNXdebTEMPLATEuuid}

                          @jchua We currently don't have a test version planned for XCP-ng 8.3. Only 8.2 is supported for the moment.

                            @ronan-a would it be too much to ask for a version for 8.3?
                            I'm testing the alpha since publication and I would like to be able to use RunX πŸ˜„

                              @Finallf It's been a while since we've been actively working on this subject, that doesn't mean that this project is abandoned, but it's not our priority target.
                              Currently it is rather this project that we are trying to move forward: https://xen-orchestra.com/blog/announcing-project-pyrgos/

                              Sorry but it's not so soon that we will have a new runx update. πŸ˜…

                                Yes, and it's not impossible that RunX will be used in Pyrgos at some point πŸ™‚
