          not sure is it distro problem, but mc is pretty broken on 8.3, same at release version.
          Arrows navigation is not working, it typing something instead.

          That probably happens because of missing ini file. https://github.com/microsoft/WSL/issues/26#issuecomment-210004998

            @Tristis-Oris indeed, I can confirm. I'm not sure about the config file because it's the same version of mc as we have on 8.2.1, where it's working.

            Maybe it needs a rebuild.

              I noticed an error message while performing this upgrade... Says we should be using UEFI from this point forward. I didn't see that in the release notes, or didn't really read that part very well. It lets you go forward but mentions that higher revisions will not be able to work in BIOS mode.

              Here's a question that probably doesn't need to be worked out yet:

              If we have old BIOS boot for 8.2.x, and we go to upgrade to 8.x.x (next LTS), are we going to be able to switch to shutdown, switch to UEFI, boot the installer, and upgrade? Or is this going to need a clean install?

                The release of 8.3 is the last version in the 8.x version series. Also 8.3 is a special release at the moment its a standard release, then at a later date its going to become the LTS (next one from after 8.2).

                The next version number after 8.3 is going to be 9.0 (https://xcp-ng.org/blog/2024/10/07/xcp-ng-8-3/ and https://docs.xcp-ng.org/releases/release-8-3/).

                  The UEFI only is going to cut off a bunch of older lab hardware, my HP DL360 gen 8 do not (can not?) have UEFI. That also means that Supermicro X9 is probably out, not sure about old Dell.

                  It's progress and as such need to move with the times, but Beta 9 is going to be a long way off for my testing it due to hardware limitations.

                    If your old Dell machines are from PowerEdge Gen 12 or later then they can use EFI (UEFI) just need to enable it in the BIOS of those servers.

                    May also be possible with your Supermicro X9, though a link to the model or the datasheet would help please?

                    The HPE DL360 Gen8 is likely definitely out unless it has a EFI option via an update. Though for sure the use of HPE DL360 Gen9 or higher will work.

                        @Greg_E All answers are actually in the release notes: https://docs.xcp-ng.org/releases/release-8-3/#legacy-bios

                        The deprecation decision comes from XenServer. Whether we'll follow the same schedule as them is yet to be decided, also depending on when they remove its support completely.

                          @john-c No UEFI on HP DL Gen8.... it too bad because they work just fine. HP DL Gen9 servers support UEFI boot. By the time XCP 9.x rolls around it will be time to trash the G8 machines anyway. But lack of BIOS boot will limit cheap lab/home machines...

                            HP says Gen9 has UEFI, and probably those are now in the $200 shipped range with 40 threads and 128gb of RAM like the gen8 were when I bought them.

                            I'll have to upgrade at some point, probably going to be a mini system next time.

                            As an FYI, I think Vsphere8 products require UEFI, I saw a notice in the instructions about this, haven't installed yet. Yes testing the competition and mostly for experience migrating off of VMware.

                              Bargain Hardware carries a HPE DL360 Gen9 for only £80, a HPE DL380 Gen9 for £80 and a HPE DL560 Gen9 for £237. Check them out! https://www.bargainhardware.co.uk

                              I used them for my Home Lab's Dell PowerEdge servers, they are really good. I haven't had problems with them or their products if I do they are very good at helping out. Also are a good source for access to components and upgrades which are hard to get!

                                @Greg_E I saw a similar thing and dealt with it thusly:

                                Upgrade the master in BIOS to preserve the configuration
                                Upgrade second (only other, in this case) host in the pool using UEFI boot
                                Migrate 'master' status to the second host
                                re-install the first host with UEFI, re-join it to the pool.

                                Before doing this take careful note of the xe pool-enable-tls-verification mentioned in the release notes. You won't be able to join the cleanly reinstalled host without it.

                                Typing 'master' so many times has me wishing we had a better word for the pool coordinator.

                                  Thanks. I will eventually need to do this on my production system, thankfully it is new hardware and should be good until I retire (next guy's problem).

                                    not sure is it XO or Xen issue.
                                    8.3 release. i changed pool master and now it unavailable.

                                      1. Is that on the released version of XCP-ng 8.3?
                                      2. What steps did you follow to change the pool master and why? Was it in the middle of the pool upgrade?
                                      3. check xensource.log around the time of the XAPI startup.

                                        2. fresh pool installation. no tasks, just master change via XO.

                                          @Tristis-Oris i tried to remove host from pool or change master, but can't execute even xe host-list with endless timeout

                                          done with

                                          xe pool-emergency-transition-to-master
xe pool-recover-slaves

                                          all vms at dead master counts as running, so i can't run them again.

                                          and can't forget host "code": "HOST_HAS_RESIDENT_VMS",

                                          upd
                                          need to reset vms with
                                          xe vm-reset-powerstate uuid=*** --force then forget host.

                                            @Tristis-Oris is the xapi daemon still running? daemon.log and xensource.log around the time you changed the master could give more insight?
