What were you trying to do that didn't work?
The Q35 + SEABIOS VM with a mlx5_vfio_pci VF can not be migrated when using seabios-1.16.3-1.el9
Version-Release number of selected component (if applicable):
host:
5.14.0-402.el9.x86_64
qemu-kvm-8.1.0-4.el9.x86_64
libvirt-9.9.0-1.el9.x86_64
seabios-1.16.3-1.el9
VM:
5.14.0-402.el9.x86_64
How reproducible:
100%
Steps to reproduce
1. create a MT2910 VF and setup the VF for migration
2. start a Q35 + SEABIOS VM with a mlx5_vfio_pci VF
3. check the MT2910 VF in the VM
4. migrate the VM
# virsh migrate --live --verbose --domain rhel94 --desturi qemu+ssh://10.73.212.98/system
The migration process is hung

> {"execute":"query-migrate","id":"libvirt-450"} <-- The migration process is hung here
5. Destroying the VM and then check the qemu-kvm log

Expected results
The Q35 + SEABIOS VM with a mlx VF can be migrated
Actual results
The Q35 + SEABIOS VM with a mlx VF can not be migrated
