        For everyone who needs to ensure usb-policy.conf remains intact after update/reboot, I have posted a workaround script here.

        Please note this is a workaround script only till a better implementation is done by the xcp-ng team.

          @stormi

          So which page do need to refer my auditor to for all the patching that is done once the kernel is EOL?

          Just in case I’ve asked Lawerence on Youtube what his thoughts are on promoting EOL products to his clients

            https://xcp-ng.org/docs/releases.html#all-releases

            Latest LTS: XCP-ng 8.2

Using the Long Term Support version is relevant if:

    you want to be sure the system will stay stable
    you want to **have all security fixes** without doing major upgrades every year
    you want a predictable migration path on a longer timeframe
    you don't care about new features coming for the next years

LTS releases are supported for 5 years.

            XCP-ng 8.2 still has about a year and 3 months left of support.

              That is not the point I’m trying to make.
              The heart of the OS is going to be end of life December this year. You can probably plaster away but you need to keep track of everything for cve’s etc.. if you don’t want an auditor to trip on this. As they will because it’s end of life.

                @xerxist The Linux kernel is not exactly the heart of XCP-ng. Xen is. Also, the threat model is different from that of a Linux distribution, because the main threat here comes from VMs (privilege escalation, information disclosure, DoS...), and this is taken very deep care of, at every level.

                XCP-ng's management network being meant to be on a dedicated network, not exposed to direct attackers, makes network attacks a lower threat but of course doesn't negate it so it still is to be taken into account.

                Your concerns are valid, especially regarding how to make an auditor accept that it is actually maintained for the scope of XCP-ng's needs, and we're looking how to document it.

                  Yesterday, as I was about to walk out of the office for a deposition, someone walked in and said the connection to oen of the VM's was dead.

                  I opened up Idrac to the Dell host (Dell Inc. PowerEdge R540) and found a black screen unlike any I've seen before with XCP-NG; my vague recollection was a standard linux screen with "system" or something like that. I had twenty minutes to get to the deposition so I didn't have time to do normal debugging so I rebooted the host and watched as it did a normal reboot. It came back and all was well.

                  Now that the dust has cleared, this is my first chance to look into what happened. Where do I start? /var/log/xensource.log? /var/log/kern.log? Something else?

                  Thanks!

                      I have been installing 8.3 beta 2 on a variety of different server grade hardware in the last week. (HP DL325, HP DL20, Lenovo SR250V2) and all have worked without issues however the issue posted by myself and @rmaclachlan above in regards to networking bonds not reporting the proper speed still remains.

                      I am also seeing lots of xcp-networkd errors in xensource.log

                        I have recently installed 8.3 beta and all update patches over it... It seems to be running fine for me (on AMD).. Should I go ahead and install XOSTOR over it and see if that works ?

                          XOSTOR isn't entirely ready on 8.3 yet (at least it's not on the latest bug fixes level)

                            So I got a weird one. I have installed the latest XCP 8.3 updates and rebooted my server. All the VM's I had on my test server worked perfectly fine except for a single Debian 9 VM that would start booting and then "power off" just as the kernel started to spit stuff on the display.

                            I banged around with it for a while and what I found is its a kernel crash somewhere when SMP is initialized. If I only give a single vProc to the VM, it boots normally and all works fine.

                            At this point, its not causing me any more problems because I jsut rebuilt the VM on something more modern (Rocky 9)

                            I have perserved this VM if the dev's would like to get more debugging information or wish to try anything. I can also capture the logs if its of interest.

                              @flakpyro If the pull request mentioned by @psafont earlier does fix it, we'll know next time we rebase on the fixed code.

                                @Anonabhar I don't think we have enough work bandwidth to investigate this, but it could be good, if you have enough space, to keep it for some time. If someone has a similar issue in the future, maybe this will prove useful.

                                    Have you, at any time, installed something outside the XCP-ng repos?

                                      Hmmmm...while I'm gonna say a guarded "I don't think so", that is a junk machine that I use to test things so that may be a possibility.

                                      How do I tell?

                                        @archw Post the output of yum repolist --verbose

                                        FWIW, read here for the proper way to install additional packages.

                                          @archw I see references to xen 4.17 in your logs. Are you currently using the 4.17 test repos or was 4.17 pushed out to the main 8.3 repos?
