The target has not seen the guest_connected event via spice_chr_guest_open or spice_chr_write, and so spice server wrongly assumes there is no agent active, while the client continues to send motion events only by the agent channel, which the server ignores. The net effect is that the mouse is static in the guest.
By registering the interface on post load spice server will pass on the agent messages fixing the mouse behavior after migration.
