[PATCH 0/3] qapi/vfio: Add VFIO device migration state change QAPI event

[Avihai Horon]

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.
