Eric, looks like we missed that vfio_listener_region_del() also needs to check vfio_known_safe_misalignment() now. "[PATCH] vfio/common: remove spurious warning on vfio_listener_region_del" sent upstream QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.
> Steps to Reproduce:
> 1. start a win11 domain with a QL41112 PF and tpm device
>
> # virt-install --machine=q35 --noreboot --name=win11 --memory=4096 --vcpus=4
> --graphics type=vnc,port=5911,listen=0.0.0.0 --import --noautoconsole
> --network bridge=switch,model=virtio,mac=52:54:00:01:11:11 --disk
> path=/home/images/win11.qcow2,bus=virtio,cache=none,format=qcow2,io=threads,
> size=20 --boot=uefi --boot nvram.template=/usr/share/edk2/ovmf/OVMF_VARS.fd
> --tpm model=tpm-crb,backend.type=emulator --hostdev 0000:3b:00.0
>
> 2. check the QL41112 PF info in the Win11 vm
> The PF works properly
>
> 3. hot-unplug the PF from the win11 domain
> virsh detach-device win11 /tmp/device/0000:3b:00.0.xml
> Device detached successfully
>
> 4. check the qemu-kvm info
>

This bug can still be reproduced in qemu-kvm-7.0.0-5.el9.x86_64
Verification: Test env: kernel-5.14.0-108.el9 qemu-kvm-7.0.0-6.el9 Test result: PASS Test step: > 1. start a win11 domain with a QL41112 PF and tpm device > > # virt-install --machine=q35 --noreboot --name=win11 --memory=4096 --vcpus=4 > --graphics type=vnc,port=5911,listen=0.0.0.0 --import --noautoconsole > --network bridge=switch,model=virtio,mac=52:54:00:01:11:11 --disk > path=/home/images/win11.qcow2,bus=virtio,cache=none,format=qcow2,io=threads, > size=20 --boot=uefi --boot nvram.template=/usr/share/edk2/ovmf/OVMF_VARS.fd > --tpm model=tpm-crb,backend.type=emulator --hostdev 0000:3b:00.0 The win11 domain with a QL41112 PF and tpm device can be started successfully > 2. check the QL41112 PF info in the Win11 vm The PF works properly > 3. hot-unplug the PF from the win11 domain > virsh detach-device win11 /tmp/device/0000:3b:00.0.xml > Device detached successfully {"execute":"device_del","arguments":{"id":"hostdev0"},"id":"libvirt-407"} {"timestamp": {"seconds": 1655190578, "microseconds": 237219}, "event": "DEVICE_DELETED", "data": {"device": "hostdev0", "path": "/machine/peripheral/hostdev0"}} > 4. check the qemu-kvm info The qemu-kvm does not throw any suspicious information like "qemu-kvm: vfio_listener_region_del received unaligned region" Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
