So I have a pcie ethernet card stubbed pci-stub.id=10ec:8168 and it appears in my win7 "edit" page. It also appears in its own iommu group 14 under "Tools/system devices". ACS Override is enabled.

But when I start the VM I get the following errors:

I'm a newbie. I've gotten up to this point only from reading the forums here. Any ideas welcome.

 

Thanks,

If your system doesn't support interrupt remapping, you can allow unsafe interrupts to occur.

 

You may need to modify the following in syslinux.cfg 

 

append vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot

Thanks!!!   I'll try that tonight.
