@andSmv Thanks for the good info! Sure if you guys provide the beta I would be more than happy to test. Unfortunately, I only have access to this hardware for another week before I need to ship it out. If you can get me the beta today or tomorrow I can get it in place and start exercising it over the weekend. Thanks!

RE: PCI Passthrough Missing Capabilities in Guest
Just a quick update, I spun up a RHEL9 guest and am seeing the same behavior.

PCI Passthrough Missing Capabilities in Guest
Hi All!
I am attempting a PCI passthrough of an LSI 9670-24i Tri-Mode RAID Card to a RHEL8 guest. Upon booting the guest I am getting a "osintfc_mrioc_security_status: PCI_EXT_CAP_ID_DSN is not supported" in dmesg. Which basically means the driver can not find the PCI Capability "Device Serial Number" and then the kernel basically shuts down the PCI device. Originally I tried different versions of the driver, changing every possible BIOS setting I could think would have anything to do with this, and after inspecting the source code of the driver the issue seems to be directly tied to a missing PCI Capability. XCP-ng is 8.3 with the latest updates as of a week or so ago.When running lspci -vvv in XCP-ng I get the following:

Capabilities: [100 v1] Device Serial Number 00-80-5e-49-ae-38-8b-18Anyone know of a way to unhide or passthrough additional capabilities over to the guest?
