      What kind of backup? Delta should work (CR and warm migration too). Only basic backup with XVAs aren't able to be restored on an older version (like many things in XAPI world, it's only forward compatible)

        This was a full backup not a delta so that makes sense. I think I need more of my lab servers to be on 8.3 so I can do some more testing. I did not find any issues and nothing broke using it so I need to try harder. 😉

          Great 🙂 In general: go for delta backup. It's faster (by a decent margin) because XVA generation is not really optimized on XAPI side. Even if you compare a first delta (so a "full") vs an XVA, it might be 30 to 50% faster to generate.

            Maybe we should incentivize with a bounty: find bugs in XCP-ng 8.3, get a T-shirt 😄

              Hello, not sure the unusual behaviour it's XCP-ng or XOA related.

              One vm does not show up in the RAM summary.

              These are the active VMs on my Intel NUC 🙂
              Screenshot from 2023-04-01 22-06-33.png

              This is the RAM summary, vm154 is missing.
              Screenshot from 2023-04-01 22-08-22.png

              Odd but not problematic, just to let you know.
              Thanks

                Hmm that's weird indeed 🤔 Do you have the exact VM missing in there? If yes, can you show the result of xe vm-param-list uuid=<UUID OF THE MISSING VM>?

                  Sure! The missing vm is vm154, the result is below:

                    I think the issue is:

                                             memory-actual ( RO): 0
                                             memory-target ( RO): 0
                    

                    Can you compare with your other VMs?

                      If anything related all VMs including the "odd one" have pv drivers and guest agent installed and working (so I think 😊 )

                        Okay so your problematic VM isn't reporting any memory used. That's weird and that's why it doesn't appear in the bar (which is using the memory used to display it).

                        So it's not an XO display bug, but something weird inside the guest. Can you restart the guest agent process or even the VM?

                          Also, the totalizer seems to be correct: 14GB, what seems to be missing is the "green" chunk related to vm154.
                          From left to right: XCP-ng 1.8GB, vm104 4GB, vm153 2GB, vm152 3GB.

                          If it can be of any help, guest tools seem to work

                            Can you do a xe-toolstack-restart and see if it's better? (this won't interfere with the running VMs)

                              @olivierlambert said in XCP-ng 8.3 public alpha 🚀:

                              xe-toolstack-restart

                              Done and it worked 😊 now all the VMs are displayed.

                              [21:24 xcp-ng-1 ~]# xe-toolstack-restart

                              done.

                              Thank you for your help, if it counts as bug it is a small one: so far 8.3 alpha has been super-solid.

                                Is it possible to take a snapshot with usb passthrough in version 8.3?

                                  @mdavico Are you asking if it's possible to get one processed, even though a USB passthrough are currently enabled/active on the KVM, or? 🙂 I think you need to be a bit more precise.

                                    I'm jumped on XCP-ng 8.3 on my bleeding edge ODROID H3+. Are there any plan to support the build in sensors in the host system at some point, so it's possible to get CPU package temperature readouts? Right now, I've not been able to make any readouts from the host-machine, where I've tried a few sensor terminal tools 😄 .

                                      @exetico I mean when you passthrough a usb, when you want to take a snapshot it gives the error VM_HAS_VUSBS(OpaqueRef:aedd32dc-6dec-4be1-aa5d-9dda799c01b2) and as in version 8.3 you can exclude certain vdi, possibly also a VUSB, that's what I mean

                                        Has anyone tried installing 8.3 on a NUC12 yet? I'm about to buy a (maybe 2) NUC12 i5 (1240P) to replace my old tower servers at home. How does XCP-ng handle the hybrid architecture?

                                          @ashceryth XCP-ng is based on Xen 4.13, so I'm quite sure it doesn't handle Intel Hybrid architecture. I'm not even sure there's ongoing efforts on this support in Xen Project Community.

                                          Moreover, after a very quick check, I didn't see the trace of ARM big.LITTLE support in recent XEN.

                                          I think this kind of features needs the profound analysis how exactly is to be mapped on hypervisor based platforms. And I think the response is not obvious at all.

                                            Yes, it will simply explode if you have both cores types enabled at the same time. You will need to disable E or P cores (your choice).

                                            The main reason is a really poor design choice from Intel, with those cores designed with similar functions doing different things. Nobody in the virt world want to deal with those.
