I found a few threads regarding this so i'd like to confirm before moving forward.

Here is my sys devices:

OMMU group 16:

[111d:8018] 07:02.0 PCI bridge: Microsemi / PMC / IDT PES12N3A 12-lane 3-Port PCI Express Switch (rev 0e)

[8086:10bc] 08:00.0 Ethernet controller: Intel Corporation 82571EB/82571GB Gigabit Ethernet Controller (Copper) (rev 06)

[8086:10bc] 08:00.1 Ethernet controller: Intel Corporation 82571EB/82571GB Gigabit Ethernet Controller (Copper) (rev 06)



IOMMU group 17:

[111d:8018] 07:04.0 PCI bridge: Microsemi / PMC / IDT PES12N3A 12-lane 3-Port PCI Express Switch (rev 0e)

[8086:10bc] 09:00.0 Ethernet controller: Intel Corporation 82571EB/82571GB Gigabit Ethernet Controller (Copper) (rev 06)

[8086:10bc] 09:00.1 Ethernet controller: Intel Corporation 82571EB/82571GB Gigabit Ethernet Controller (Copper) (rev 06)

 

I would like to hide pci id 09:00.0 and 09:00.1 so I can make 09:00.0 and 09:00.1 specifically available to a pfsense vm (lan / wan interfaces).

 

Questions:

 

1) Is it a safe assumption that the PCI bridge 07:04.0 should be hidden as well? 
2) My edits would be to the unraid os section and look like this?

 

Unraid OS:

kernel /bzimage
append xen-pciback.hide=(07:04.0)(09:00.0)(09:00.1) initrd=/bzroot

 

The result i'm assuming:

Unraid OS would see:
PCI Bridge:  07:02.0

NIC: 08:00.0

NIC: 08:00.1
 

PFSense VM would have the ability to leverage 07:04.0, 09:00.0 and 09:00.1

Please let me know if I'm doing this right and the outcome is what I believe it to be.

*bump* hoping someone can confirm this for me. 

I too would like to hear about this as well as I have an r710 and my groups are somewhat similar and assume I could pass 2 of the 4 ports through...
