    @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

    Made some updates to this project. Any existing users please see note. I have also updated the initial post. ️ Upgrading from an earlier version of this script? Read this first. This version bumps the config schema to v2 (adds PUBLIC_URL and ENCRYPT_REDIS_CREDENTIALS) and corrects two config.toml generation bugs. Your xo-config.cfg is migrated automatically and non-destructively, but the corrected /etc/xo-server/config.toml is only written by --reconfigure. Run --reconfigure once before resuming normal updates: ./install-xen-orchestra.sh --reconfigure This regenerates config.toml with the fixes (your old file is backed up first; data in /var/lib/xo-server is untouched). It is strongly recommended if you set both REDIRECT_TO_HTTPS=true and REVERSE_PROXY_TRUST — that combination previously produced a duplicate [http] section and silently dropped one of the settings. Afterwards, run --update as normal for routine XO updates — --update does not need to be preceded by --reconfigure again. Also added option to adjust Xen Orchestras memory allocation. Useful if you are getting out of memory errors or added more memory to XO. ============================================== Xen Orchestra Memory Allocation ============================================== Setting Value ----------------------------- ----------------------------------- Total system RAM 5399 MB Current xo-server heap limit 4887 MB Recommended heap limit 4887 MB

    Thanks for the ping and for narrowing it down; that live-migration repro is a really useful signal. I don't know enough about how the guest tools report IPs back through XAPI to say where the canonicalisation should happen, but it sounds like something @Team-Hypervisor-Kernel might want to look at since the trigger is on the agent side after migration. If it turns out to be reproducible on another Windows guest version (2022, 2019), that might help narrow it further; no pressure though, you've already done the hard part.

    Dug a little deeper. For a VM where the disks are not shown the following XO API call fails: /rest/v0/vms/a519e879-3971-9210-51b6-7df14336e7b7/vdis { "error": "no such VDI ac37700d-3157-4df7-b8e8-e1799a994591", "data": { "id": "ac37700d-3157-4df7-b8e8-e1799a994591", "type": [ "VDI" ] } } Also the VDI cannot be retrieved over the XO API: /rest/v0/vms/a519e879-3971-9210-51b6-7df14336e7b7 ...

    Unable to import Backup Config from Community Edition to XOA Deployed Appliance

    Ok I think I have resolved the issue. It appears that if you do not activate either a paid license or the trial, it fails with the import because many of the features are not active until you enable the license and then update the XOA appliance. Once I activated the trial and then updated the appliance again, I was able to successfully import the backup. My hesitation with activating the license before importing the config as the licenses are bound and I didn't want to have to redo the setup if the config did not import. Again, it looks like I need to activate the license first and then I can import the config.

    Just to close the loop on this: XO 6.4 (released on April 29) includes a specific fix for VNC reconnection, which may have been causing keyboard focus loss and, in turn, modifier keys to get stuck (PR #9727). At least, that’s my understanding; I could be completely wrong, so please take it with a grain of salt. If you’re on XO 6 and still seeing the issue, upgrading to 6.4 may help.

    Good news, or at least, that's my understanding. This was a known bug and it's fixed in XO 6.4 (released April 29, PR #9681). Upgrading should make those alerts disappear for good. Thanks for the video, it made the report unambiguous.

    load-balancer : Affinity to Host groups

    Mitchel-APDM
    @olivierlambert In my understanding, Anti affinity tags only looks for the tags that are attached to the VM. For example: Datacenter 1 Host 1 VM1-1 Host 2 VM1-2 Datacenter 2 Host 3 VM2-1 Host 4 VM2-2 VM1-1 and VM1-2 should be able to migrate to Host 1 and Host 2. VM2-1 and VM2-2 should be able to migrate to Host 3 and Host 4. But VM1-1 and VM1-2 should never be able to migrate to Host 3 and Host 4. VM2-1 and VM2-2 should never be able to migrate to Host 1 and Host 2. With the current (Anti) Affinity tags, it will only look to the tags attached to the VM, so in the example it would be possible for VM1-1 to go to Host 4, if VM2-2 would be at Host 3 together with VM2-1. But if we could tag the hosts, it would not be possible for VM1-1 and VM1-2 to be on Host 3 and Host 4

    @olivierlambert +1 For creating vApps GUI in XO Reason: I recently had this configuration: VM1 - Delay 90 Seconds VM2 - Delay 100 Seconds VM3 - Delay 0 Seconds The VM3 instead of starting first, always starts last without fail. One difference I noticed is that VM3 is UEFI vs VM1 & 2 being in BIOS mode. I read elsewhere in the forum that vApps is the only reliable way to have an order. Maybe if we can somehow ensure that delay works, vApps will become less significant ?

    @Bytevenidos That's an interesting way of doing this, I'll have to remember it. I think the Fuel Ignition tool has a vhd output, it also produces both ignition and combustion parts for you. Worked pretty good on one test machine, but I need to go deeper into some of the other choices you can type in.

    @omatsei said: @omatsei I figured out the problem. There appears to be a bug in XO that requires you to check "Check Certificate" and/or "Start TLS", save the configuration, then uncheck them, then save again. Then it should work. The bug is that they're unchecked by default, but apparently they're enabled in the background. Thanks for that, I was stump on this one trying to reconfigure a new instance. This is defintely the case even with the latest auth-ldap (v0.10.11) plugin.

    @geometry game 2 This usually happens when dependencies are out of sync after pulling updates. Did you try removing node_modules and the lock file and then running yarn install again before starting XO?
