Dear reader,
I am trying to set up a qemu virtual machine to capture an ethernet device on
my little PC. My understanding is that this is possible with vfio-pci. Googling
around has lead me to the following configuration being added to config.scm:
(operating-system
(locale "en_US.utf8")
(timezone "Europe/Vienna")
(keyboard-layout (keyboard-layout "us" "altgr-intl"))
(host-name "guix")
(kernel-arguments (append (list "vfio-pci.ids=8086.125c")
%default-kernel-arguments))
(initrd-modules (cons* "vfio_pci" "vfio" "vfio_iommu_type1" "vfio_virqfd"
%base-initrd-modules))
Alas, guix system reconfigure now exists with an error.
root@guix ~# guix system reconfigure /etc/config.scm --allow-downgrades

I am unable to determine why linux-modules.drv fails.
Can you please enlighten me what I’m doing wrong?
Thank you,
Konrad
