I have looked at both of these posts and still having some issues.

I have gotten the 2 ports that I want off of both controllers hidden but its not showing up in the VM port area under available pci devices on the VM section.

 

I had first tried: vfio-pci.ids=8086:1528, 8086:10fb 

But it had hidden the whole network card and thankfully I was able to get to the web gui via the SFP+ port. 

Then I have tried: xen-pciback.hide=(03:00.1)(81:00.1)

and it hid the correct ports that is wanted but its not showing them available for the VM side.

 

I am wanting to pass through one port from the x540 and one from the SFP+ for PfSense.

 

Thank you for the help in advanced.

I had followed this guide to get all the details along with the others posted below.

 

 

Have you tried editing the VM XML with the following:

 

Quote

 <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x03' slot='0x00' function='0x1'/>
      </source>
      <alias name='hostdev2'/"
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x81' slot='0x00' function='0x0'/>
      </source>
      <alias name='hostdev3'/>
    </hostdev>

 

So when you press edit VM you should see both ports checked on the Other Pci devices drop down list. 

I think he is trying to use 1 of the ports on a NIC for a VM. This is my issue too. Is it possible to split a dual NIC so one port is used by unraid and the other port can be available for an unraid vm?
