        They removed the Hypervisor tag from their blog, so finding that posts isn't easy anmore and CH/XS posts get lost in stuff I don't care about.

        Looks a bit like they only want to keep it because VMware Horizon becomes more attractive, if Citrix doesn't bring it's own HV for XenApp/XenDesktop for free.

          Citrix want to keep their HV/platform because they don't want to rely only on competitors to run XenApp/XenDesktop. It's just not a "product" but a technical part of their solution.

              Its all about XA/XD I'm afraid but it does state year end 2019 for the next LTSR.

              https://www.citrix.com/blogs/2019/09/19/whats-new-with-citrix-virtual-apps-and-desktops-september-2019/

              "Long-Term Service Release News

              For those of you on 7.15 LTSR β€” one of our most popular releases β€” we have some exciting news about our next LTSR availability. We’re planning our next LTSR for year-end."

                Somewhere they said they want to algin numbers and XA/XD LTRS only makes sense on a fitting CH LTSR.

                    Hi, is the "raw-device-plugin" branch already working?
                    https://github.com/xcp-ng/xcp-ng-xapi-storage/tree/feat/raw-device-plugin

                    I just upgraded to 8.0 and wanted to try it now and found out, that the latest released package is v1.0.2 and is missing the raw-device.

                      @ronan-a is still working on it, and he's in the middle of a load of tests/benchs.

                            @olivierlambert @ronan-a Has there been any update on this development? I do see an update to master in org.xen.xapi.storage.raw-device from feb 2020. is it more safe to test now?

                              SMAPIv3 isn't production ready yet (we aren't really happy with the current state of it). Also because we are working on LINSTOR storage with LINBIT, it takes a lot of our storage R&D/resources right now. We can't be everywhere, so we have to prioritize…

                                Ok, thanks for the update. Wasn't expecting production ready, was just curious on status and if was safe to run tests with it which sounds like not.

                                      We'll let you know when visible things will be out. But yes, we work on it.

                                        I am playing a bit with SMAPIv3, I created a storage of type file in /mnt/ and a VM, after restarting xcp-ng /mnt/ was not mounted so the storage was not mounted, I did it manually and when starting the VM Throw me

                                        Error code: SR_BACKEND_FAILURE_24
                                        Error parameters: VDIInUse, The VDI is currently in use
                                        

                                        I did a detach to the disk from the vm and I also deleted the vm and created a new one but it still gives the same error.

                                        detach and repair does the same

                                          Am testing ext4-ng and noted that the vdi's it creates are not matching their uuid on filesystem. If I look at the ext4 file structure itself they are simply labeled 1, 2, 3 etc.
                                          -Good news is I could create a 3TB vdi on this sr within xoa without having to use the command to force it as raw

                                          I tried a raw-device sr but still get error that driver not recognized. Assuming plugin still not in

                                            @olivierlambert said in SMAPIv3 - Feedback & Bug reports:

                                            You need to get rid of SMAPIv1 concepts πŸ˜‰ If you meant "iSCSI block" support, the answer for right now: no.

                                            It's a brand new approach so we'll take time to find the best one, to avoid all the mess that had SMAPIv1 on block devices (non thin, race conditions etc.)

                                            I think the next big "device type" support might be raw (passing a whole disk without any extra layer to the guest).

                                            Ages ago (in the 1980s), I experimented with raw disk I/O on VAX systems using QIO calls. Yes, it's fast, but also doesn't take bad block or deteriorating disk sectors into account. I can't recall offhand if there way a way to at least update bad block lists or if you had to start from scratch.

                                            Are there better mechanisms these days to handle such things as read/write errors and re-allocation to good blocks if bad blocks are detected on a running system?
