    Good-day Folks, Running the XenClean.exe utility that ships with xcpng-winpv-9.1.146.0-Release-x64, on a Windows Server 2022 VM (Version 21H2 - OS Build 20348.5020) with Citrix Guest Tools v9.4.2 installed, results in the following error and a subsequent BSOD with stopcode = INACCESSIBLE_BOOT_DEVICE: [Alert] Cleanup FAILED: -2147467259 Msiexec failed with code 1605 [Interactive] Cleanup task status is Error [image: 1776933189945-screenshot-2026-04-23-043239.png] Also, contrary to what's stated in the release notes, the VM does not automatically reboot. I suspect that's a consequence of the utility not completing successfully to trigger the reboot. ULTIMATE SOLUTION FOR ME (might be different for you) : Mount any Windows ISO to the VM (I used the Windows Server 2022 ISO) Navigate to the Advanced tab of the VM and change the boot order so DVD-Drive is first (don't forget to click Save) Press any key, as prompted, to trigger a boot into the ISO Press next and select "Repair your computer" On the next screen select "Troubleshoot" and then "Command Prompt" You will now have a command prompt open and at the X:\ drive Type C:\ and hit enter to drop to the system drive for the installed OS Navigate to the folder holding the XenBootFix utility. For me it was C:\Users<MyUser>\Downloads\xcpng-winpv-9.1.146.0-Release-x64\package\XenBootFix Type XenBootFixe.exe C:\Windows and wait for the utility to finish, then reboot the VM. Install the XCP-ng Windows Guest Tools and reboot when prompted. After the VM boots back into Windows, confirm on the VM's General Tab that you see the message Management agent 9.1.145-77 detected. Don't forget to go back into the VM's Advanced tab and disable the DVD-Drive under Boot Order. Sharing this, in hopes that the Vates team will see and address this issue, and it might help someone else out of a jam.

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    Continuous Replication -> Exchange Log

    @mts said in Continuous Replication -> Exchange Log: If you use the native windows-backup or a third-party application it will delete the transaction-log after backup. How can I achieve the same with xen-orchestra? I'm running low on disk-space right now... I think that you confusing physical (layer) backup with logical backup. XOA can backup/replicate/snapshot phisical medium which is a hard disk presented to your VM. It has nothing to do with the data in the VM (logical layer).

    Hmm I think it might be possible using xe CLI and creating the drives manually (creating VBDs I suppose). I never spotted such a use case before, but again, might be doable It is using VNC (via noVNC in XO). You can copy a template, but a template is just a set of "configuration" for your VM (eg PV or HVM mode, some virtual BIOS settings).

    Hi, If you are using XOA, please create a support ticket. This way our teams could take a look remotely to find the best solution.

    Thanks for the tip. I was using node v8.11.4 and had issues compiling during the upgrade then upgraded to the latest stable node version which wasn't v8.x. I upgraded to v8.16.2 now and it runs fine. Thanks.

    Indeed, 6.2 uses a very old configuration for keyboard mapping and therefore doesn't work correctly with XO.

    I switched due to SSD replacement and XCP-ng new installation. I didn't think about that switching from ext3 to lvm does also have an effect from thin to thick provisioning Anyway I found the explaination, here -> "a snapshot on a LVM based SR will double the whole VM disk size!" But I will think about to switch to ext4 -> topic solved, thank you!!

    Change the remote in your job config. If you want to keep the previous backup there, just move or copy everything to the new remote.

    No it's not how it works in XAPI. You need a dedicated ISO SR using only *.iso file name/extension.
