Maybe you would need to logout and login again from the graphic
session. Or manually start it, not sure.

See "spice-vdagent --help", specifically -f and -o options.

With all SPICE stuff properly installed, everything works out of the box: clipboard, resizing, file transfer from host to guest. With "properly installed" I mean: installed SPICE drivers manually from virtio-win ISO by loading them since the Windows installation beforehand, then once booted into Windows downloaded the vdagent ZIP from spice-space website and manually installed the service according to instructions.

I'll check, maybe is not handled by driver but agent
