    @tjkreidl said: @john.c Not found with the Wayback Machine, alas. Still not finding it anywhere else, but will keep looking! It's a crying shame Citrix didn't preserve the treasure trove of old community blogs. I did a bit of digging with the aid of AI and I’ve managed to uncover the original three blog posts of NUMA and references to UMA. If you do some more digging you may be able to uncover the rest, so it can be rewritten and/or updated, then be hosted somewhere that won’t go down so easily, or be lost as easily. If you do an update or write etc, may I suggest switching the images used to WebP or AVIF format, will seriously help file size while maintaining their quality (or even giving room for higher quality). Consider switching to SVG for diagrams rather than raster (or as the default). I’d suggest checking out to consider using Mermaid for diagrams (https://mermaid.ai/open-source/?utm_medium=hero&utm_campaign=variant_a&utm_source=mermaid_js). Maybe if you do a rewrite use markdown and something like Hugo, to generate it from the files to host on GitHub or some other pages providing repository (e.g. GitLab Pages or Codeberg Pages). https://web.archive.org/web/20220527221535/https://www.mycugc.org/blogs/tobias-kreidl/2019/03/07/tale-of-two-servers-bios-settings-affect-apps-gpu https://web.archive.org/web/20220527213026/https://www.mycugc.org/blogs/tobias-kreidl/2019/04/30/a-tale-of-two-servers-part-2 https://web.archive.org/web/20220527215004/https://www.mycugc.org/blogs/tobias-kreidl/2019/04/30/a-tale-of-two-servers-part-3 https://community.citrix.com/forums/topic/235895-xenserver-vm-citrix-worker-sizing-question/ https://xcp-ng.org/forum/topic/9359/cpu-provisioning https://community.citrix.com/forums/topic/237493-memory-and-cpus-assigning-to-vms-in-order-to-obtain-maximum-performance-according-to-numa-topology/ https://community.citrix.com/forums/topic/241553-bios-power-performance-settings/ https://community.citrix.com/forums/topic/243640-citrix-hypervisor-performance-tips/

    @gcpeters4 said: @john.c This is a good idea as well. If the previous suggestion of trying to do a DNS round robin approach doesn't work, this may be my best option. Thanks for taking the time to provide your suggestion! By the way my suggestion is recommended best practice from Microsoft for their Active Directory software and/or technology. My suggestion will be more likely to work if your DNS servers and requests have issues with Round Robin configuration. Plus with my solution you can easily add more servers as domain controllers to the cluster, as required and use replication to keep them consistent and up to date.

    @Pilow said: @LoTus111 nice, but could be better you're missing the additionnal step in the TIPS section here : https://docs.xen-orchestra.com/xo5/troubleshooting#memory upgrading XOA to 8Gb is not enough, you have to tell xo services to be able to use this additionnal RAM. Question is if XO is built with 6gb initially does one still need to addjust memory via the command? Or only if expanding after the fact? Edit - to answer my own question and for others. After adding this function to my script it does appear the XO will setup appropriately with deployed with 6gb ram initially. ============================================== Xen Orchestra Memory Allocation ============================================== Setting Value ----------------------------- ----------------------------------- Total system RAM 5399 MB Current xo-server heap limit 4887 MB Recommended heap limit 4887 MB

    @olivierlambert said in Continuous Replication fails with VDI_IO_ERROR(Device I/O errors) on fresh XOA install after XenServer 7.2 -> XCP-ng 8.0 upgrade: To your config file, yes. Where this config file is depends on where do you installed Xen Orchestra (I suppose from the sources, so I can't guess where do you installed, could be anyware ) edit: I think it's fixed now and integrated by default in the config Great, this fix already is in the new version. I was having this problem (Error: VDI_IO_ERROR(Device I/O errors)) and was not be able to do CR of my VMs but now CR works. Thank you PS: BTW that was my config file

    When you click on the link of the error message it should send you to the official documentation, explaining what it means: https://xen-orchestra.com/docs/backup_troubleshooting.html#error-messages I'm not sure to understand the UI question, can you post a screenshot?

    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.
