I have /etc/conf.d/modules configured to load the kernel modules vfio, vfio_iommu_type1, vfio_pci, and vfio_virqfd.

/etc/init.d/modules successfully loads these modules, and can be verified by passing:
Code:

# /etc/init.d/modules/ restart
 * WARNING: you are stopping a boot service
 * Loading module vfio ...                                                                               [ ok ]
 * Loading module vfio_iommu_type1 ...                                                                   [ ok ]
 * Loading module vfio_pci ...                                                                           [ ok ]
 * Loading module vfio_virqfd ...                                                                        [ ok ]
 * Autoloaded 4 module(s)
#_


However, when verifying with lsmod and grep

Code:

#lsmod | grep vfio
#_


Visually inspecting the lsmod output also shows that none of the 4 modules have loaded.

Manually using modprobe returns the same result. The modules are apparently unloading themselves the first chance they get.

:x How do I correct this behavior?

MudcrabMearchant,

Welcome to Gentoo.

Maybe the modules don't load correctly?
After you modprobe one of those modules, what do you have at the end of dmesg?

Dmesg gets nothing added to its tail after passing "modprobe vfio" or "modprobe vfio_iommu_type1"

I went over my kernel config again, and realized that I had built the modules into the kernel. So it was working as designed.
I made the assumption that I had built these as modules the last time I configured my Kernel.

How Embarrassing. :oops:

Thank you NeddySeagoon for your help.
