@florent Sure, but I can only do it over the weekend. Also, I'll try to check if the script built the correct branch. First time using the script to build anything other than master. On a side note: recently some other strange errors started to show up "Body timeout Error". These are plain full backups to a remote with disaster recovery for another cluster, that always worked fine. Also, in this case, the timeout defined within the job doesn't cancel the job and the remaining jobs in the sequence don't run. Haven't had the time to dig into this - when I do, I'll start a new forum post. [image: 1783089319496-790bd845-1932-4f33-abfd-36441d720aa1-image.jpeg] Cheers, Pedro

Is there anything mentioned in the motherboard or service manuals, about where if one PCIe slot is occupied another is running at reduced speed when occupied? Something like this is in the manual for a Gigabyte B450 Aorus Elite (Rev 1.0) motherboard, for example. Can be in yours, somewhere written on one of its pages.

@the_jest Not showen in this picutre but this is where the message would be displayed. Next to the name of the host... [image: 1782931263879-screenshot-2026-07-01-144023.png]

Meant to update this again last night - as a road map for those who might try similar at some point: This community's documentation led me to some relevant information on mouse/keyboard pass-through. Namely, if you want this to work you have to pass the entire PCI controller through to the guest(s), Won't work with motherboard devices. But I'm out of PCIe slots. What to do... Simple. Chuck the two serial adapters and install two dual USB 2.0 adapters in their places. Connect the keyboard/mouse to one of the ports and a 4/8/16 port USB to serial adapter to the other. Then pass the entire controller through. In this particular server (R810) I have 5 available PCIe slots. Two will be used for the video cards, one for a 4x NVMe to PCIe adapter (which is eventually where the VMs will reside) and the remaining two for the USB interfaces. This effectively gives me two discrete physical systems, a third available VM instance (say, for network management, monitoring or whatever) and the XOA instance. For application/radio control systems hypervisors (nested) I'll probably have 2ea Win11 and whatever flavor of Linux that supports the GT730 GPU on the system - each assigned the pass-through devices - but only two running at any given time. So no resource contention issues. As far as the displays: I have the main interface of the server connected via SIP to a 2160AS KVM. I'll take 2 more SIPs and use these as the keyboard/mouse inputs for the USB cards. Video...I use an HDMI active splitter on other systems in the network so I'll employ that here. One of the ports on the add-in GPUs goes to the splitter, one of the splitter outputs goes to the SIP via HDMI to VGA adapter and the other feeds the main ceiling mount monitor. The Primary display will be replicated to the KVM screen. Resolution isn't an issue as I have a video scaler inline with the KVM for just this scenario. The concept could be expanded. I'm looking at picking up a T630 and building 4 effective "systems" out of it, following the same principle. The 630 has 8 available PCIe slots. Will update when the next batch of hardware arrives - or I get the Linux side of things sorted. That's next.

PRs upstream are in review

Hello @mgr42 I can confirm that indeed today AMD iGPU passthrough is not working on XCP-ng. I am currently (slowly) working on it. There are other references about this topic in the Forum and on GitHub FYI: https://xcp-ng.org/forum/topic/11918/amd-barcelo-passthrough-issues-any-success-stories https://xcp-ng.org/forum/topic/8909/issue-to-load-gpu-passthrough-invalid-pci-rom-header-signature-expecting-0xaa55-got-0x4556 https://github.com/xcp-ng/xcp/issues/806 https://github.com/xapi-project/xen-api/commit/930ffb34e42d674b8234c3d8399fdba97efa6b38 On the setup I am working on, the Expansion ROM is provided indeed by firmware via the VFCT ACPI table. I dumped it to a file and provided it to qemu-dm xen-pci-passthrough device via the romfile= argument (via a modified XAPI build). I can now indeed see a ROM bar in the guest but unfortunately its content is not the content of the file therefore nothing works (amdgpu driver is unable to get its ROM and fails). So now I'm debugging qemu to try to understand the issue with the emulated/passed-through ROM BAR. Regards, Yann Kernel & Hypervisor team timemaster5 created this issue in xcp-ng/xcp open Unable to set romfile for xen-pci-passthrough devices #806 0 freddy77 committed to xapi-project/xen-api CA-418993: Enable PCI ROM BAR before attempting to give permissions to the VM Currently the VM is not able to access the ROM as the host ROM BAR is disabled and not set.

Great! I think this is really the best possible approach to make it clean

@olivierlambert Thanks for the response, much appreciated. I'm getting ready to file a bug report, as I noticed this morning that this issue is now causing a VDI-IN-USE error; preventing me from starting a VM. Fortunately, that VM isn't critical, so I want to report it and help with the troubleshooting that will lead to a fix before it spreads.

@Pilow no.

I already tried to create an ACL with user/tag/group with advanced permission but it release a full permission on the pool and it cannot be delivered to the team. if anyone know a workaround to fix it.. I appreciate that. As RBAC ACL is implemented for Xen Orchestra 6 you’ll likely find this more possible than currently on Xen Orchestra 5.

Actually after latest XO update I also started to see "body timeout error". Interestingly on my metadata backup job.

I'm doing some testing on my RAID since it appears to be a RAID VDR52: The consistency check found inconsistent parity data on Virtual Disk 1 on Integrated RAID Controller 1. Buffer I/O error on dev dm-9 Buffer I/O error on dev dm-5 Buffer I/O error on dev dm-7 async page read I will keep everyone posted

Thanks, I made the feedback to the XO team, this will be fixed ASAP.

@andibing said: I'm seeing this on XOA: xoa@xoa:~$ sudo xoa-updater --upgrade ✖ { message: 'missing string at offset 151' } xoa@xoa:~$ Unless the sun has got to me, I don't seen any other references to this error. And Gemini was confused too! Any thoughts? Can you please run “df -h” to start? If either / or /tmp/xoa-updater are low on space please increase disk space or run a clean up. The disk space on the VM and/or the SR may be too low, for the update to succeed. The XOA update metadata cache may have become corrupted and need to be cleared, before re-attempting the update. Checking the logs will help to determine if that’s the case.

For your storage question, it's fully explained in the doc: https://docs.xcp-ng.org/storage/#-how-to-modify-an-existing-sr-connection And yes, it's planned to get the complete error visible in XO, sadly, it's not "obvious" since the error message isn't returned by XAPI when you try to start but by another method we need to call after it fails ("assert can be started here" from the top of my head). Let me ping @julienXOvates
