    @tmnguyen You can open a support ticket and request that we reactivate your XOSTOR trial licenses to match your existing XOA trial.

    @Pilow Yeah I was following your post. At first I thought i was having random backup issues with backups via proxies with the occasional issue with backups via xoa. Then just yesturday see the error about memory. For now I just rebooted XOA and it down under 2gb currently. Will wait and see how long for it to build back up again or untill Dev team finds a solution to the problem.

    @comdirect Use this command: (replace sda in the command below with the relevant device) cat /sys/block/sda/queue/scheduler The active scheduler will be enclosed in brackets. e.g. noop deadline [cfq] For multiple drives use: grep "" /sys/block/*/queue/scheduler

    @redakula said in Coral TPU PCI Passthrough: Frigate.nvr which is one of the popular uses for the Coral do not recommend it for new installs either. Frigate updated their recommendations because of the Google decision to sunset the device and because there are alternative options available to frigate for image inferencing. The coral is still supported though, and frigate is not the only use case or platform that can benefit from an accelerator. At the end of the day if you've already got the hardware, and it's efficient enough to run, then not using it is a waste or resources that could be allocated to other VMs.

    @vates-11940382 Hi All at Vates, I just wanted to say a big thank you for the MCP support that’s now landing in Xen Orchestra. This is definitely a genuinely forward-thinking move, and it’s going to have a huge impact on how IaC tooling interacts with XCP-ng going forward. MCP gives XO a clean, structured, read-only interface that modern AI-assisted tools (e.g Pulumi Neo, Copilot, Claude, Cursor, etc.) can understand natively. That’s a massive step toward making XCP-ng an AI-visible, AI-navigable platform - something no other virtualisation stack is doing yet. What’s even more exciting is the long-term implication: this kind of openness and clarity is exactly what hyperscalers have been struggling with internally. If Vates continues down this path, it’s not unrealistic that MCP-native infrastructure could start attracting interest from much larger players - whether as customers, collaborators, or contributors. The combination of: IaC MCP AI-assisted operations and XCP-ng’s open architecture Puts Vates in a very strong position for the future. Thanks again for pushing this forward. It’s a big deal, and it’s going to unlock a lot of possibilities for the community.

    Difficile de parler de « réalité » avec les benchmarks. Vérifiez aussi l'iodepth (qui dépend du type matériel que vous avez, sur du flash/NVMe vous pouvez monter à 128 ou 256), la latence entre en compte aussi bien sûr. Le bottleneck principal est le monothreading de tapdisk, si vous testez sur plusieurs VMs différentes la somme va monter de manière assez régulière.

    @stormi Thank you so much. Only now getting around to setting up another set of R660s, will let you know how this works. Edit: worked beautifully on a new set of R660s. Using the old 20250606 ISO, the BCM57414 were not detected. The new ISO works as expected (BIOS install, did not attempt UEFI) and the NICs are all enumerated properly.

    Thank you every visitors and for those who did not had the chance to visit fosdem check this report: https://xcp-ng.org/blog/2026/02/19/fosdem-2026-follow-up/ [image: vates-xcp-ng-at-fosdem-2026-1.webp] One question, I promised to forward to the forum, how many VM are you running on XCP-ng ? Dozen, hundreds, thousands or more ?

    @AtaxyaNetwork Hi yes, Sorry I'm not super experienced in this area at all. I'm SSHd into the host and just ran dmesg -T in the root. [image: 1771509732474-0583e493-4d70-40b7-afc0-a88b0d9fd1a4-image.png]

    Hello everyone ! I rebuild a new OME appliance with the latest version (4.6) Dell decided to give this appliance Proxmox, Nutanix and OpenShift compatibility, but no XCP-ng yet... If someone from Dell want to reach out about this, please contact me ! [image: 1771504614561-7f4cc1c1-90c4-4f30-94f8-cf109711cfd6-image-resized.png] What i did on the rebuild: Via live CD add xen-blkfront and xen-netfront driver, and rebuild the initrd change root password activate SSH. Via SSH sed -i -e 's/sda/xvda/g' /opt/dell/omc/utilities/tui/bin/ome_disk_config.sh sed -i -e 's/sda/xvda/g' /opt/dell/mcsi/appliance/scripts/appliance_resources.sh bash /mnt/Linux/install.sh # To install XCP-ng tools As usual, please send a DM if you want the link to the VHD Feedback is welcome ! (Disclamer: This build is something I create on my free time and to help people who have difficulty running Dell appliances on XCP-ng. I do not guarantee a fully functional appliance, but I do my best to make it work. If you have a support contract with Dell and require official support for OME, please contact Dell and request compatibility with XCP-ng.)

    We do upgrade drivers, especially via alt, it's pretty safe (LTS doesn't mean frozen drivers). @stormi could confirm.
