@ovicz Hello, does the igpu passthrough work with an up-to-date Ubuntu 26.04.1 guest?

@fred974 Hello, Could you please provide the logs produced by XenClean after its execution? If your VM couldn't boot after XenClean, XenBootFix executed from a recovery environment should get your VM working again. Instructions are available here: https://docs.xcp-ng.org/troubleshooting/windows-pv-tools/#windows-fails-to-boot-hangs-inaccessible_boot_device

@poddingue Quick update: I disabled “Purge snapshot data when using CBT” in the XO replication job. I still see NBD+CBT displayed in the XO task manager during replication, but after letting the jobs run for a few cycles, last night’s Veeam backups completed without any CBT warnings or fallback to full. I’m going to add a couple more VMs and continue monitoring. We use Veeam as part of our overall backup strategy for regular VM backups, and switching away from it would be a fairly large project. Veeam doesn’t provide the XCP-ng replication we need, so we’re using XO specifically to maintain replicas at our other site which is why we are using both products.

FYI, our approach with vectura is only temporary, we have other plans in few months to get rid of this potential cat & mouse game Broadcom could do by slightly change their protocol (without even talking about the potential legal risk with it).
