What's the device you're trying to assign and the scripts you're using
to do so? vfio-pci is fully supported, but I'd recommend a kernel newer
than 3.11 (maybe a newer QEMU too, you didn't specify a version) unless
openSUSE is specifically pulling vfio features and fixes into their
distro. vfio does work with OVMF, most of the testing of this is with
GPU assignment. It does require an OVMF image built from a fairly
recent tree (not more than a few months old), but if you're getting into
the guest OS you're probably fine. Provide more details and I can try
to help.
Thanks, the device is a mass storage device that I work on; it's in
iommu group 1 so the script I'm running is:
for i in $(ls /sys/kernel/iommu_groups/1/devices/); do
echo $i | sudo tee \
/sys/kernel/iommu_groups/1/devices/$i/driver/unbind
VEN=$(cat /sys/kernel/iommu_groups/1/devices/$i/vendor)
DEV=$(cat /sys/kernel/iommu_groups/1/devices/$i/device)
echo $VEN $DEV | sudo tee \
/sys/bus/pci/drivers/vfio-pci/new_id
done
I started out trying to use the version of qemu that openSUSE provides
which is 1.6.2 but I also built 2.1.2 from source and that didn't help.
In terms of OVMF, I've tried an OVMF-pure-efi.fd binary from
https://www.kraxel.org/repos/jenkins/edk2/ as well as building a debug
OVMF.fd binary from the edk2 project
(https://github.com/tianocore/edk2/commit/23a2df76783ad7694918916f28e24cd1a1f84daf).
If you think it might help, I can certainly install a newer kernel.
