Hello, This series adds a new QAPI event for VFIO device migration state change. This event will be emitted when a VFIO device changes its state, for example, during migration or when stopping/starting the guest.
This event can be used by management applications to get updates on the current state of the VFIO device for their own purposes. A new per VFIO device capability, "migration-events", is added so events can be enabled only for the required devices. It is disabled by default. Feedback/comments are appreciated, Thanks.
