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 ?

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?
