GPU Passthrough does not work after yum update.

[wennmbj]

Hello together,

I did a setup to passthrough my VGA on my Centos 8 machine according: https://www.server-world.info/en/note?o ... p=kvm&f=12

Everything was working fine until I updated my machine by yum update.
Now I am getting the error meassage:
qemu unexpectedly closed the monitor: 2020-01-20T17:10:21.555493Z qemu-kvm: -device vfio-pci,host=06:00.0,id=hostdev1,bus=pci.3,addr=0x0: vfio error: 0000:06:00.0: failed to setup container for group 20: No available IOMMU models

My IOMMU settings seems ok:
