    Hello, I'm new to the world of XCP-NG/XO so this might just be a case of new user missing something obvious. I've not got a clear answer from a search of the docs/forums, so figured it was worth asking. I'm running XCP-NG 8.3 on my host. I'm managing it with Xen Orchestra from sources (commit 8d39f). I've got a VM that I'd like to use for some basic Ollama/Openwebui tasks, so want to passthrough the Nvidia GPU from the host. I'm not using Ollama/Webui 24/7 so I'd also like to dynamically allocate RAM so that I don't have to consistently throw large quantities of the hosts RAM at it. For this reason, I configured the VM with the following memory setup: Static: 1 GiB/48 GiB Dynamic: 16 GiB/48 GiB When the VM is running, this configuration appears to work. I have the GPU passed through and the dynamic memory allocation set. When I stop the VM and attempt to start it again, the boot fails with the error: Error from xenguesthelper: Populate on Demand and PCI Passthrough are mutually exclusive If I adjust dynamic to be 48 GiB/48 GiB the machine will then boot. Once booted, I can then once again apply the desired dynamic config of 16 GiB/48 GiB. Am I misunderstanding the configuration options and this is just not supported, or have I stumbled across a bug?

    @ferrao Yes it is. At the end the task disappears unless there is an error / failure.

    Thanks for your feedback, we'll discuss internally if there's any other possible approach (and I'm not sure).

    Hello, I suggest you look also for Packer to build ready to use VM templates, with cloud-init, guest tools, and the softwares you'd need. There's a blog post for this https://xcp-ng.org/blog/2024/02/22/using-packer-with-xcp-ng/.

    @olivierlambert said in XOCE - Language not keep when i come back (surrely dumb question): Why? I mean you are the first person to ask this. It's more work to do that and I'm not sure to really see the value A cookie is the perfect simple way to store info that are from your same browser/session, so it's very logical. Yeah, I don't see the value in having to keep a user preference within XO itself either.. just don't clear your cookies. It's what they are meant for.

    @payback007 said in vm start delay - does it work yet?: unfortunately "start delay" is not working as expected. The function what you marked above is to change the start delay of an existing "vApp". Here is an example of my setup: [image: 1558128450595-04e7439d-6b92-4356-aa23-14d704588be3-grafik.png] The value whould change the "Delay interval" later by XOA, nothing else. Otherwise is vApp feature also not working on my XCP-ng installation, I think it was never really tested. If you want to implement start delays to your VM's you can follow this guide: define vApp for autostart in xcp-ng center including start order find out the uuid of the vApp: xe appliance-list write autostart script containing #!/bin/sh xe appliance-start uuid=uuid-autostart-vApp implement new systemd.service in /etc/systemd/system/autostart.service [Unit] Description=autostart script for boot VM After=graphical.target [Service] Type=simple ExecStart=/path/to/your/autostart-script.sh TimeoutStartSec=0 [Install] WantedBy=default.target enable the service systemctl enable autostart.service Editing of boot delay time is then possible via XOA which is already a nice feature at all for "fine tuning" or adapt if new VMs are added to the autostart vApp. @olivierlambert whould it make sense to open an additional feature request? vApp-implementation was several times discussed with no "final statement" I think. When I have a pool without HA, how could I use this script? I thought about setting the script on the master server. However, in a maintenance, where a second node becomes the master, will I have to recreate the script?

    It looks like this issue occurs only when saving the backup to non-block storage. When saving to block storage ("Store backup as multiple data blocks instead of a whole VHD file: ON"), it does not, at least in my environment.

    @merango said in XOA Install Issues: @merango Hi DustineB, Thanks for the help, after looking at the BIO, I have a question around the management server. I have a spare windows 11 Pro PC that is running a Hyper-V Ubuntu 24.04.1 bare install. Can I follow your guide to install this as the MGMT server for my XCP-NG host on the same LAN? I'd prefer to manage it on a separate PC if possible and that would work nicely if that is possible? Of course you can, anywhere you can install Debian or Ubuntu can you install XO. Be it physical or virtual.

    For information : The downgrade change nothing. The only solution was to reinstall xcp with the upgrade option (even if it was up to date before the bios update) If we go back to the original problem, the latest version of the Bios changes nothing (there is no information about the BIOS on the Host page)

    @Danp it turns out I had a typo that took me forever to find . . . 102 vs 192 in the gateway ip. The strange thing to me was that the internal networking was working (pings, connections, etc). But there's something in the xoa web site that could not make the connection to the server it was running on, which makes me think there is some kind of external communication going on for server connections. If xoa can ping the dom0 then why would it need the gateway to connect to it for the web interface? Anyway I fixed the typo after finding the error running ip monitor, and then everything works great. This was the 3rd or 4th install of xoa so I was getting a bit hurried . . . next morning it took 2 minutes to find the error. Now its registered and working.
