      I just pushed a batch of updates to the 8.3/base repository.

      You can update your 8.3 testing hosts with yum update, and reboot.

      There isn't much on the side of user-visible changes, but this catches up with several months of changes made by both the XenServer team and us. Things are mostly evolving under the hood, so at this stage what matters is that the changes did not cause any regressions. Our internal test suite passed successfully.

      Let's mention a few key changes from a very long changelog, though:

      • All latest security fixes
      • Performance optimizations in XAPI components. This means better performance for dom0 in various situations. This doesn't change the performance of VMs themselves, unless they are in situations where their performance was impacted by XAPI.
      • Basic vTPM support (no snapshots, no migration, no HA...). We haven't tested it yet so I can't guide you towards testing it yet.
      • Various fixes, as always.
      • Work on HTTPS support for all operations (for example storage migration) so that port 80 can be eventually closed. A lot was done, but I'm not sure it's complete yet.
      • Beginning of transition from python2 to python3: a few scripts ported to python3, and so python3 is now installed alongside python2 in dom0, and code will be ported progressively.
      • Various driver updates

        @stormi Hi, sounds great 🙂

        I tried to use the vTPM Management and it seems for me that I am either missing updates (but I have even testing repo enabled) or the feature daemon is missing this entry:

        restrict_vtpm

        When I try to manage vTPM it generates this error on the server:
        Raised Server_error(FEATURE_RESTRICTED, [ restrict_vtpm ])

        Last added online I see Cloud:
        https://github.com/xcp-ng/xcp-featured/blob/master/bin/v6_server.ml#L68

        Would be great to be able to configure it somehow, even add custom features in a config file, there already exists an similar issue entry for it:
        https://github.com/xcp-ng/xcp/issues/184

            @stormi Both host of my playlab are happy with the 73 patches applied by yum update and reboot 👍 . I assume that a rolling updated with XO would have worked as well 🤔

              Hello.
              After applying the 73 patches there is a pending task:

              xe task-list
              
              uuid ( RO)                : 32fc65c5-3faa-ff27-662d-7cde2f630377
                        name-label ( RO): xapi events
                  name-description ( RO):
                            status ( RO): pending
                          progress ( RO): 0.000
              

              It is still there after applying the most recent updates a day ago.
              Progress stays at 0 forever.

                @kaeptn I asked a XAPI developer who told me it's expected: it's the new way to watch over VM events from xenopsd to update the metadata". The positive counterpart is this removes a lot of spurious "INVALID_SESSION" errors from xensource.log caused by the former way of doing it.

                  There's a pending enhancement which might remove the task from the database and thus be more transparent.

                    @cocoon Could try with xcp-featured from the xcp-ng-testing repository? It should enable the feature.

                    yum update xcp-featured --enablerepo=xcp-ng-testing

                        Thanks @cocoon

                        So, I just pushed two updates to the 8.3 repositories, that you can get with a simple yum update:

                        • xcp-featured, which enables partial vTPM support
                        • guest-templates-json-*, which adds VM templates for RHEL 9 and derivatives.

                          OK, TPM is visible in Windows Server 2022 but no secure boot atm.
                          Bios says it is disabled. Installed it in a virtual XCP-NG VM on ESXi.

                            @cocoon Did you enable Secure Boot on the VM, and did you also install SecureBoot certificates on your pool? (and if you installed the certificates to the pool after you first started the VM - with or without SB, you also need to install them to the VM by putting it in user mode: varstore-sb-state user {VM-UUID} varstore-sb-state {VM-UUID} user).

                              Ah yes, thanks, that works 👍
                              the command is just slightly different:

                              varstore-sb-state {VM-UUID} user

                                If you want to push the vTPM test further, you can activate bitlocker in a Windows VM and see if after a reboot the drives are decrypted without having to enter passcodes manually.

                                  @stormi That was my plan, Bitlocker feature is already installed, will test this yes 😉

                                    Small Announcement / Testing Guide

                                    There is a new and easy way for you to help testing XCP-ng 8.3: a few test scripts from the Xen project which deserve to be run on a wide variety of hosts. You don't need to run them on every host if they are truly identical, but it's good to run them on a wide range of hardware.

                                    The first one is XTF (stands for Xen Test Framework)

                                    Be aware that some of the tests may sometimes cause the host to crash.

                                    XTF

                                    Enable HVM FEP on the host. This is not mandatory but if you don't, several tests that require it will be skipped:

                                    /opt/xensource/libexec/xen-cmdline --set-xen hvm_fep
                                    reboot
                                    

                                    Build XTF

                                    yum install gcc git -y
                                    git clone git://xenbits.xen.org/xtf.git
                                    cd xtf
                                    make -j8
                                    

                                    (Optional, protects your host from a crash if its hardware is vulnerable to XSA-304) Switch EPT superpages to secure mode:

                                    xl set-parameters ept=no-exec-sp 
                                    

                                    Run the tests

                                    # self test
                                    ./xtf-runner selftest -q --host
                                    # all tests
                                    # -q stands for quiet. Remove one or both if you want to see details.
                                    ./xtf-runner -aqq --host
                                    # check return code. Should be "3" which means "no failures but some tests were skipped":
                                    echo $?
                                    

                                    Switch back EPT superpages to fast mode, if needed

                                    xl set-parameters ept=exec-sp 
                                    

                                    There will be a few SKIPPED tests, but there shouldn't be many.

                                    Known skipped tests:

                                    • test-hvm32-umip test-hvm64-umip: skipped if the CPU is not recent enough to support UMIP.
                                    • test-pv64-xsa-167: always skipped
                                    • test-pv64-xsa-182: skipped in default configuration.

                                    You can ignore them.

                                    xen-dom0-tests

                                    The testsuite is very limited in Xen 4.13, but let's still run what's available.

                                    Install:

                                    yum install xen-dom0-tests
                                    

                                    Run

                                    /usr/libexec/xen/bin/test-cpu-policy
                                    # check return code. Must be 0, otherwise this means there was a failure.
                                    echo $?

                                      @stormi I am afraid my playlab host (Dell Optiplex 9010, Intel i5-3550 CPU) is to old to contribute to the XCP-ng 8.3 alpha testing, but I run the XTF test with this results:

                                      [h01]# ./xtf-runner selftest -q --host

                                      followed by

                                      Combined test results:

                                      I have some HP Elitedesk 600 G6 mini coming in to test as a small virtualization lab (i5-10500T, 6 cores, 12 threads, 2.3 GHz base clock, 64GB RAM). Not the target infrastructure but will add to the range of hardware.

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

                                        It's an alpha not because it's unstable 😉 Just that we can make some updates before the official release. Happy to see it works well!

                                        A thought. Is there a planned list of stuff that we can vote on to have on the next release?

                                          Hi,

                                          No/not yet/our backlog is already too full to make many choices for something that should be out in a matter of months.

                                          I mean, changing a color somewhere is OK, but anything else is not in the realm of possible for now.

                                            @stormi My first HP Elitedesk 600 G6 Mini arrived (i5-10500T, 6 cores, 12 threads, 2.3 GHz base clock, 64GB RAM, 256GB NVME) and XCP-ng 8.3 alpha installed and updated right away (but I have the efi: EFI_MEMMAP not enabled message with a boot delay).

                                            The XTF test on this non-enterprise hardware returns

                                            [M01]# ./xtf-runner selftest -q --host
                                            Combined test results:
                                            test-hvm32-selftest                      SUCCESS
                                            test-hvm32pae-selftest                   SUCCESS
                                            test-hvm32pse-selftest                   SUCCESS
                                            test-hvm64-selftest                      SUCCESS
                                            test-pv64-selftest                       SUCCESS
                                            

                                            and

                                            [M01]# ./xtf-runner -aqq --host
                                            Combined test results:
                                            test-hvm32-umip                          SKIP
                                            test-hvm64-umip                          SKIP
                                            test-pv64-xsa-167                        SKIP
                                            test-pv64-xsa-182                        SKIP
                                            [M01]# echo $?
                                            3
                                            [M01]#
                                            

                                            Have not done anything else with this unit yet.
