      I throw down one of my xcp-host to setup a not-nested-virtualized xen-8 in order to test RBD speed. Performance are about 4x slower than they should be but at least it run almost like a standard local disk.

      dd if=/dev/zero of=./test.img bs=1G count=1 oflag=dsync
      1+0 records in
      1+0 records out
      1073741824 bytes (1.1 GB) copied, 1.86156 s, 577 MB/s
      

      1G is usually a really bad test, as pretty small things can influence the result massively.
      You should run tests with 10 or better 100 - if you can.
      That also diminishes influence of any caches (on source and target!).

        @Prilly XCP-ng 8.0 (the Host) is not released (even not an alpha or beta), I only released XCP-ng Center 8.0 (the Windows Client)

          @Prilly the same thing I'm wondering what could be wrong with that cpus beside of high power consumption which is obvious becouse those cpus are about 7 yrs old.

          VmWare is working with that cpu but 6.7 installer says that the support for that cpu will be dropped. And that would be not good for me becouse I would need to replace all of my servers which is not the case.

            I hope XCP-ng will support legacy CPUs as I have E5-24XX series servers ๐Ÿ˜ž
            I guess they will work fine but as they are not supported officially ...

            E5 arent legacy. Xeons x5xx are.

              According to the XS HCL Citrix Hypervisor 8.0 is supporting Dell R420 servers but not Dell R430 (same model, but newer, you can still buy the R430). The newer R440 is also supported. This seems very odd to me. Has anyone any idea why this is the case?

                While you're waiting for XCP-ng 8.0 beta, what about testing the latest security update to help us release it fast?

                Thanks!

                  Been running CH 8.0 for a week to test it out. There's an issue with the guest tools. performance is slow because the guests I/O isn't "optimized"

                  going to revert back to xcp 7.6 today.

                        Guest tools on Windows (I suppose) aren't working well?

                            Have you used Citrix tools directly from CH ISO or something else?

                              yes, I used the ones in the ISO and through the system. I also tried some older ones.. In the end the system never recognized that I had the proper ones installed. Tried with 2 different windows VMs. Server 2016 and Win10

                                  @nuts23 did you use fresh installed windows or "used" ones?

                                    @Prilly I installed Citrix Hypervisor 8.0 on my Dell C6100 which is running L5630 CPU and it booted just fine.

                                      @crash you can even try with XCP-ng 8.0 now ๐Ÿ˜‰ (still beta but will be useful to try)

                                        @olivierlambert @prilly Just loaded the XCP-ng 8.0 successfully on a Dell C6100 with 2 x L5630.

                                        No errors during install, and boots up just fine for use.

                                          Thanks you guys for testing the l5630 cpu, this gave me confidence to upgrade my dell r610 with 2x x5675 cpus with hypervisor 8.0, upgrade was done with iso and cd and the upgrade process went very smooth, server boot up and everything seems almost nice.

                                          i did notice it load cpu microcode rev 1f on boot, i also notices systemd is throwing a error on boot: systemd failed to load kernel modules, this has no impact and the host is running fine with no error other than that. i suspect the error might be related to upgrade fra 7.6, i will try to reinstall 8.0 as a fresh install and see if this clears the kernel modules stuff.

                                            From what I see in https://www.intel.com/content/dam/www/public/us/en/documents/corporate-information/SA00233-microcode-update-guidance_05132019.pdf X5675 CPUs are not supported by Intel itself anymore, so no mitigation for you for the MDS attacks ๐Ÿ˜•

                                            And that's why no vendor can say they "support" it anymore, since no one can guarantee the security of anything running on them now.
