--- Comment #12 from Chesn  ---


FWIW, setting

iommu=soft

got rid of the journal spam in my case (found here)

full disclosure: i don't care about virtualisation (i only ever messed around
with it to check out gnome boxes) and i've disabled kvm and kvm_amd (even
blacklisted the modules in a file /etc/modprobe.d/blacklist_kvm.conf), even
disabled virtualisation in BIOS while debugging this issue (none of which
worked)…

good luck with fixing this, guys!

regards,
M.

Did a rough count of the number of messages spamming the journal: 660/sec

Neither virtio nor numad do anything with the IOMMU (AMD-Vi) either.

Unless you're trying to do PCI device assignment, KVM doesn't have any
dependency or interaction with the IOMMU.  General IOMMU issues would probably
be better served reporting them to the IOMMU mailing list:
https://lists.linuxfoundation.org/mailman/listinfo/iommu

If you are attempting to do PCI device assignment, please provide details
including VM configuration (XML or qemu launch scripts) and dmesg prior to the
AMD-Vi spew.

Forgive my ignorance, but does your guidance also apply when using virtio
drivers or numad?
