          @Andrew I pushed a test build of Xen in the testing repository for XCP-ng 8.3, which will hopefully solve the crash situations the tests found on your two servers.

          Quoting @andyhhp about what the crash message means: "The guest has tried to turn on LBR, but I don't know what that means on this CPU" where LBR stands for Last Branch Record and is used for debugging and in anti-cheat software in video games.

          yum clean metadata --enablerepo=xcp-ng-testing
          yum update xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools --enablerepo=xcp-ng-testing
          reboot
          

          If I understood correctly, the patches add support for more recent CPUs (Sapphire Rapids) and at the same time make it so that now when guests attempt to turn LBR on, this does nothing (but at least doesn't crash).

            NUC 11 (i5-1135G7) running xen-hypervisor.x86_64 0:4.13.4-10.36.0.sapphirerapids.1.xcpng8.3 no longer gives the crash error. The test runs but it still generates a Xen message:

              @Andrew Those are normal.

              Bad rIP is actually an error introduced in XSA-170 because someone misread the Intel manual. I've been trying to delete it upstream for years now. Its been so long that Intel nearly released a feature which would have required us to delete that check, and I successfully persuaded the Intel documentation team to add a footnote clarifying the statement which was misinterpreted during XSA-170.

              At some point in my copious free never, I should restart the argument to delete it upstream...

              The other two are logging from the XSA-260 fix. There's an error(/misfeature) in the x86 architecture and those would have been privilege escalations before the fix was in place. I decided when fixing XSA-260 that such attempts shouldn't be entirely silent, hence the one-liner. That particular printk() is actually common with other debugging routines, so can occur during regular development.

                    Tried on my Intel NUC11ATKC4 with N5105 and 32GB of RAM.

                    spec from Intel site.

                    I know it's an edge case, nevertheless here the results:

                      @rRobbie Thanks. This look like the same crash as discussed just above, with a candidate for a fix provided, if you want to test it. It should be included in the next update of the Xen packages anyway.

                        @stormi Here's results from one of my lab servers. I'll run on some newer hardware next week.

                          Wow! It's been a while I didn't heard about those ones 😄 11 years old CPU, and still usable, impressive 😄

                            I guess the old G5 is getting a little too old to keep running... but it does still work.

                                @Andrew Intel E5450, that's very retro.

                                It's also first-gen VT-x and doesn't have HAP, which is why the test that is looking explicitly for HAP doesn't work.

                                As a stopgap, remove hap from the VARY-CFG := hap shadow line in tests/invlpg/Makefile and rebuild. In the meantime I'll try to figure out a nice way to cope with this.

                                    @stormi Hello.

                                    Just installed the latest patches to the XCP-NG host and did the test again.

                                    Not sure the fix was already included in the packages... So just for your info 😊

                                        So, a few days ago, we pushed the following updates to XCP-ng 8.3:

                                        • guest-templates-json-*: adds Ubuntu Jammy template.
                                        • XAPI updated to version 22.34. Among other things:
                                          • the host's webpage, when accessed on port 80, now automatically redirects to HTTPS on port 443 rather than displaying a 403 Forbidden error. Note that in a future update, port 80 may be completely closed instead.
                                          • I haven't checked yet, but I think this removes the immortal pending xapi events task that a previous update added, while keeping the perk of the previous change, which removed a lot of spurious "INVALID_SESSION" errors from xensource.log (almost anyone having had a look at the logs has seen them).
                                        • xcp-featured: was simply rebuilt for the updated XAPI
                                        • microsemi-smartpqi vendor driver updated to 2.1.20_035
                                        • sudo patched for security issue

                                        No need to re-run the Xen tests if you ran them previously, as Xen wasn't updated in this round of updates. If you haven't yet, then the "let's cover the largest range of hardware possible" action continues.

                                          A test was recently pushed to XTF's repository which may crash a host whose hardware is vulnerable to XSA-304 (hardware vulnerability related to EPT superpages).

                                          There are two modes in Xen regarding EPT superpages, fast vs secure, and XCP-ng defaults to fast due to the big performance hit secure would have by default on affected hardware. The vulnerability may allow an HVM guest to crash the host, and this is what the test demonstrates.

                                          I've updated the small Xen testing guide above with instructions to switch to secure mode before running the tests, if you want to avoid the crash in case your host is vulnerable.
