      This sounds OK to me. I think your issue is related to something else, please display the VM record (xe vm-param-list uuid=<VM UUID>

        @olivierlambert How can I show that param if I'm getting error during my attempts to create a VM?

          So the VM isn't created at all? You really need to give us more info. What template are you using? Is it working if you don't add an ISO?

              Yes, this error:

              INTERNAL_ERROR((Failure "Expected string, got 'N'"))
              
              This is a XenServer/XCP-ng error
              

              happens when I click create.

                    @burbilog said in xoce INTERNAL_ERROR while trying to create VM:

                    INTERNAL_ERROR((Failure "Expected string, got 'N'")

                    You have to investigate on your XCP-ng host, there's obviously a problem in there.

                    See https://xcp-ng.org/docs/troubleshooting.html

                    I would suggest to restart the toolstack too.

                        You have duplicates in XAPI DB, that's not normal 🤔

                        It's coming from a template I assume.

                          @olivierlambert But templates are stock templates, no? It does not matter what template I choose, it fails anyway.

                          How to fix them?

                            I have no context on what you did on those hosts previously, so it's hard to answer what to do to assist.

                            I don't know what could trigger that in the first place 🤔

                              @olivierlambert I did not do anything on these hosts, except occasional yum update. Frankly, i did not touch this setup for a while and it worked a month or two ago ok.

                              I'm kinda surprised that all 3 servers do the same. One of them wasn't touched at all except yum update since it worked ok.

                                It's normal you have the problem on the whole pool/all hosts, because the XAPI database is shared with all hosts.

                                I would search for duplicate keys for platform record on all your existing VMs.

                                  @olivierlambert So, how to look up these keys? I ran xe vm-list and xe sr-list on all hosts, it seems that all UUIDs are different.

                                  I even reinstalled one of the hosts, set up 8.2.1 anew and the problem here persists.

                                    Again, reinstalling won't change anything since the info is within the main DB, which is copied on all pool members from the master 🙂

                                    You need to find duplicates UUIDs in all your VMs objects.

                                      @olivierlambert I ran xe sr-list and xe-vm-list on all hosts, compiled a list of uuids, sorted them and all of them are unique. How to search for duplicate keys then?

                                        @olivierlambert installed xo-cli, connected and ran xo-cli --list-objects , then grepped all uuids, stirpped everything else and tried to find dupes -- none. all uuids are unique there.
