I want to pass through 2 of the 4 ports for my integrated 4 port NIC. I have a dell r710 server.

Right now eth1 used to access unraid and unraid things.

I want eth 3 and eth4 for wan and lan for pfsense(vm on unraid)

I tried following spaceinvader videos but wanted to double check.

Image 2.png is normal IOMMU group settings.

Image 1.png is I set VM manger > PCIe ACs override to both.

If I add 14e4:1639 to the flash boot wont it ignore my NIC card? Append vfio-pci.ids=14e4:1639 initrd=/bzroot

Trying using this but no go.

 

 

I added this and still no go.

 

Here is the error message 

 

You're not providing enough information. Need to post diagnostics (tools>diagnostics) after you get the error.

Here is VM logs.

It boots fine if i remove this from the VM XML.

found your problem in the logs, or at least, the next step in your problem:

 

Feb 18 08:09:39 Ruby kernel: vfio_iommu_type1_attach_group: No interrupt remapping support.  Use the module param "allow_unsafe_interrupts" to enable VFIO IOMMU support on this platform

go to the first post in the thread below and modify your syslinux.cfg to what it says in regards to unsafe interrupts, reboot, and try again. If it fails again, post a fresh set of diagnostics immediately after the vm fails. I can tell you from personal experience that "allowing unsafe interrupts" has caused me zero issues.

Awesome thank you. I will test and report back

 

Solved: I turned on "allowing unsafe interrupts" and everything is working great. Thank you!
