        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.

                @olivierlambert This problem is common for all 3 servers, i did not touch other two hosts at all for a while. I see some strange error appear in xensource.log after VM creation attempt:

                This problem is common for all servers.

                  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.

                                    @burbilog ah, no, there are some repeated, i had to sort it first. but there is a lot of uuids that are repeated.

                                        @olivierlambert Ugh.

                                        I erased xoce (rm -rf /opt/xen-orchestra && apt purge redis-server), then reinstalled both xoce and single server afresh. Then I connected brand new, shiny xoce to brand new, shiny server. Only. I did not connect other servers.

                                        And I've got the same problem. Added NFS SR, tried to install VM, pink square, error:

                                        Perhaps, it's a problem with some latest changes to xoce after all?

                                          Could you try with XOA? This is more and more intriguing, never heard or had this before.

                                            @olivierlambert Installed xoa appliance, connected it to that server and it seems to work, xoa creates new VM just fine. So, it's certainly a problem of xoce.
