What were you trying to do that didn't work?
Hotplug a vfio-pci device to the qemu instance, the qemu hit core dump.
Please provide the package NVR for which bug is seen:
host kernel: kernel-5.14.0-392.el9.aarch64+64k
guest kernel: kernel-5.14.0-392.el9.aarch64+64k
QEMU version: qemu-kvm-8.1.0-5.el9.aarch64
edk2 version: edk2-aarch64-20230524-4.el9_3.noarch
How reproducible:
always
Steps to reproduce
- Launch a guest without NICs and with virtio-iommu
