So I am running into a snag when trying to pass some quad NIC ports through. When I do the PCI stub thing I actually disable all of my NICS and am unable to connect. For some reason both cards are in 8086:1521 c1:00.0 and .1 are my onboard that I still want unraid to see.

 

Thoughts?

 

 

Onboard NIC:

 

IOMMU group 59
    [8086:1521] c1:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
IOMMU group 60
    [8086:1521] c1:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)

 

Quad NIC:

 

IOMMU group 11
    [8086:1521] 01:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
IOMMU group 12
    [8086:1521] 01:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
IOMMU group 13
    [8086:1521] 01:00.2 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
IOMMU group 14
    [8086:1521] 01:00.3 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)

Use the below instead. Then you can specify the PCI address instead of the ID.

Remember to change it to your numbers.

 

xen-pciback.hide=(08:00.0)(08.00.1)

It will probably not show up in the other pci device list, so you have to edit the xml and add it.

So the OS still sees the interfaces.. should they be hidden from the OS? I was supposed to put that in the syslinux.cfg correct?

looks like I had a . where a : should have been. looks like they are hidden now.

Its not really hidden, but no drivers loaded. And there is a error in the code tag I inserted with a . instead of a :. I'll edit it when on a PC. No luck on a tablet... So blame me for the error you made  And I'll blame the page I copied it from 

So a new wrinkle. Since I made that change I can't start any CentOS based VMs. I get an immediate kernel panic. I am going to try and reverse the change and see if they will boot again. I get a panic on a new install of centOS as well. 

Ok I was able to confirm the problem is unrelated. 

I am able to confirm that this worked for me! Thanks for the help!!
