    @gregbinsd let us know. If you do use my script. It pulls nodejs from NodeSource so it may not install the latest 24.15.0 tls. If you specific 24.15.0 it will install that version. If you need to change node version with my script use the rebuild option.

    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

    Do you mean to say when you edit the network config box, and fill it out with your own network info (adhering to this standard: https://cloudinit.readthedocs.io/en/latest/topics/network-config-format-v1.html) that cloudinit in the vm gives a yaml error? This indicates the way you filled out the entry box is not properly formatted. Keep in mind to pass networking info, your cloudinit install in your template VM needs to be set to use nocloud data sources, and keep in mind the network configuration passed via cloud-init is added to the template VM, not replaced, so you need to properly configure your template VM to not already have adapters configured with IP addresses etc

    Yes, you are right infact the old instances are halted and are temporarily kept till I am not sure the imported ones are perfectly working on new node. Unfortunately in the meantime I need a way to manage boths and it means xencenter or cli. Thanks for having pointed my attention to the duplicated uiids problem.

    See me previous post here -- https://xen-orchestra.com/forum/post/5072 I'm guessing that you were missing the symlinks for the plugins, otherwise they should have been present in XO.

    I think the simplest way to just do this once is to go to Settings > Config, there you can export the backup. Once you create your new instance of XOCE, you can import the backup using the same page, then just logout of the default user, and you can login using your old credentials. Make sure to delete the admin@admin.net account after.

    So you can't create a backup with XOA Free. This edition is meant for all usual administrative tasks, like XCP-ng Center if you like. If you want backup features, 2 choices: going for XOA Starter, Enterprise or Premium depending on your backup needs. See each edition features here: https://xen-orchestra.com/#!/featuresmatrix (each edition comes with pro support, updater and remote SSH access if needed) install XO from the sources on a system you like, following our guide: https://xen-orchestra.com/docs/from_the_sources.html

    @axel I just ran the installation script on a Debian 10 VM and it worked as expected. Even when using the "official" way, sometimes the installation can fail due to things like -- issues with recent commit to github repo issues with upstream dependency etc This is why the pre-built XOA appliance exists. Feel free to open an issue over on the script's Github repo if you continue to encounter issues.

    This is a 3rd party container not validated nor endorsed by XO devs. We don't know what's inside, if you have questions on it, ask on the Github repo of the maintainer Backup reports will answer your initial question/requirement (reports can be sent by email, Slack etc.) There's also a Nagios plugin, or you can use XO API to make request to be support in any software of your infrastructure Monitoring a Docker container is outside scope of XO, I would suggest to ask Docker community. Regarding XO and how backup are done, any fresh XOA deployed (or from the sources) will be able to find all the previous backup done by an old XOA, because we store every info on the remote.

    The best option is to use Disaster Recovery, or both DR with your current backup. It's the easiest way. Please watch the video I posted.

    I think this is what happens when you ask XOA to move a disk into a different resource pool, and that pool can't see the storage. Discovered that by accident

    Olivier - the destination storage was attached to the wrong pool. It was behaving correctly, but not doing what I wanted.
