    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 same as @john.c and also XO Lite tends to be less a priority because less critical than the full fledged XO (the priority is to replace entirely XO 5 in the next releases). Why you would need XO Lite outside basic actions? It's mostly meant to bootstrap XO itself and do basic operations (which is already the case, at least with many basic features already). Initially, the goal hasn't moved: replacing XenCenter. We are moving in that direction, but again, I think it's more important to get XO 6 finished first. I'm curious to understand more the use case of XO Lite in your context @unreal-shizzle ?

    Hi, everyone Thank you for your help. I had a flux that was blocked by our firewall. The button worked after that. But it doesn't explain why I lost this configuration and had to reinstall it. Thanks again.

    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.

    Hello, We tried the compression feature. You "can see" a benefit only if you have a shared storage. ( and again, the migration between 2 nodes is already very fast, we don't see major difference, but maybe a VM will a lot of ram ( >32GB ) can see a difference. If you don't have a shared storage ( like XOSTOR, NFS, ISCSI ), then you will not see any difference because there is a limitation of 30MB/s-40MB/s ( see here: https://xcp-ng.org/forum/topic/9389/backup-migration-performance ) Best regards,

    Migrating from XCP-ng Windows guest tools to Citrix

    I did it that way so as to get the old Citrix driver first, and then let it update and watch it reboot. That was my logic anyway. @dinhngtu said in Migrating from XCP-ng Windows guest tools to Citrix: @bberndt Okay, I managed to reproduce your situation. I think it's because the "driver via Windows Update" option was enabled after installing the XS drivers, which caused the drivers to lock onto the non-C000 device and prevent updates from coming in. Normally, XenClean should be able to fix the situation. But if you want to fix things manually, or if things still don't work (C000 is still not active), here's a procedure that should fix the problem: Take a snapshot/backup/etc. Keep a note of static IP addresses (if you have any; there's a chance those will be lost). You can also use our script here: https://github.com/xcp-ng/win-pv-drivers/blob/xcp-ng-9.1/XenDriverUtils/Copy-XenVifSettings.ps1 Reboot in safe mode and disable the non-C000 device. Reboot back to normal mode; it'll ask you to reboot a few more times. The C000 device should now be active and you should be able to get driver updates again. (Optional) You can now enable and manually update the non-C000 device (Browse my computer - Let me pick).

    Do you have any SR using a VM? (like an ISO SR in a NFS share inside a VM). This is freezing NFS and makes host taking half an hour to restart. Logs should tell you why the RPU failed if it failed

    It's impossible to answer right off the bat without knowing more in details what's going on. HA is a complex beast, and combined with HCI, requires a lot of knowledge to find what's causing your issue, between both xha and XOSTOR. In other words, it is very demanding to analyze all the logs and trying to make sense of it. However, I can give you some clues to make sense of it: The HA log is at /var/log/xha.log. When you shutdown a host, you should be able to watch (on each host) what the HA is deciding to do. My gut feeling: there's maybe a XOSTOR issue making the heartbeat SR being unavailable, and so all hosts will autofence Then you need to understand the XOSTOR logs for why the cluster wasn't doing what's expected. My best advice: remove HA first, and only then investigate on XOSTOR. Kill on node (not the master) and check if your VMs are still able to start/snapshot/write inside.

    PXE Boot from new VM not working

    @JBlessing as it looks like it does start, it looks like the networking side is working, at least at first. Just for debugging purpose you could try to switch that VM to BIOS instead of UEFI if it is possible, maybe it is related to what the pxe is starting in the VM. You could also try switching the VM between realtek and e1000 NIC, at this stage, PV drivers are not there so it is using an emulated NIC, maybe the image your PXE starts doesn't like the one you're using and it gets stuck somehow. As you're already using it with vmware, I assume you know how to size your VM, but if you went for a tight RAM value for this VM, you could try to give it more RAM to see if that could be related, as everything has to fit in RAM at some point, we may be using more at startup than vmware… Hope one of this can help

    About the xsconsole: sometimes it's not refreshing. You can try to get access to the console, then type "xsconsole" it will start it and you should see it works You must have the master up to date if you want your slave to connect again. I never tried to elect a new master in the middle of the upgrade, I would discourage it. Better shutdown some VMs on the master, upgrade it and you are automatically back on track.

    @Danp yes I ran "yum update" to be sure but "nothing to upgrade" on the pool-master. I try with storage (iscsi) NIC configured and without Storage NIC configured but the pool join freeze. Seems that persist some "SESSION" (may be referred to the slave host previously configured?) or some incoerence in the pool database... from /var/log/xensource of the slave host when try to join the pool: "session_check D:520c5b4e5b36 failed with exception Server_error(SESSION_INVALID, "

    @olivierlambert Agreed. The Citrix forum used to be very active, but especially since Citrix was taken over, https://community.citrix.com has had way less activity, sadly. It's still gratifying that a lot of the functionality still is common to both platforms, although as XCP-ng evolves, there will be continually less commonality.

    For anything older than the branches still shown in https://pkgs.alpinelinux.org, (from v3.0 to v3.12), the packages should be downloaded from their cdn: https://dl-cdn.alpinelinux.org/alpine But as mentioned above, anything older than 3 releases from the lastest current one(v3.21) are end of life and should not be used for more than testing.

    I already suggested you the solution, now it's up to you to live with those process or to decide to reboot (ideally after doing updates because it's very dangerous to NOT being up to date)
