@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.

@acebmxer welcome to freedom.

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]

I had same problem, about last 2 weeks, but is is about Xen update, after apply last update, Backup of Windows VMs works again.

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.)

Any news about issue?

@acebmxer There are older versions of the guest tools still available on Github.

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

@florent No problem, just thought it would be fun. Thanks for your work anyway!

@florent do the logs i provided help at all? or Idea why i am see this issue as well? I do not have a DR job just Delta backup and mirror backup.

Thanks for the heads-up and thanks for the help !
