Hi,
   drag&drop from host to guest should work, not the opposite. Note
that there's an option to pass to spice-vdagent to enable drag&drop
(from host to guest).

It also relies on a virtio-serial PCI device and a dedicated spicevmc char device to achieve communication between the guest and the host. These devices must be added to the virtual machine for the agent to work in the guest.
