What were you trying to do that didn't work?
The virtio-keyboard device not work with prewhql-265 or later version.

Please provide the package NVR for which bug is seen:
qemu-kvm-9.1.0-1.el9.x86_64
kernel-5.14.0-522.el9.x86_64
edk2-ovmf-20240524-7.el9.noarch
virtio-win-prewhql-265
Guest OS: Win11-24H2

How reproducible:
100%

Steps to reproduce
1.Start a Win11 VM and add a virtio-keyboard device(iommu=off)
2.Install prewhql-265 or later version driver
3.Check if the keyboard is work

Expected results
Keyboard works well

Actual results
Keyboard not works

Additional info:
The virtio-keyboard device works well with versions pre-whql-264 and lower, regardless of IOMMU status.
How to enable iommu: Add '"iommu_platform": true, "ats": true' to the qemu command line
