Short summary: vdagent is the in guest agent, under windows vm's there
are two executables (vdservice and vdagent) but we refer to them sometimes
as vdagent collectively. Under linux its two executables as well (spice-vdagent
and spice-vdagentd). VDI port is the old transport host<->guest, vioserial
is the new. The reason for the change is that vioserial was already in qemu,
and VDI port would have needed to be accepted, and doesn't have any benefit
technically (except for being tested, but vioserial is being used by everyone
so it will be just as or even more tested).

You could test the agent - I don't think libvirt supports installing it, so
you need to do this manually. It should be on spice-space.org. You will need
changes to the commandline though:
 -device virtio-serial -chardev spicevmc,id=vdagent,debug=0,name=vdagent
 -device virtserialport,chardev=vdagent,name=com.redhat.spice.0

You can change the debug setting. In the guest:
 windows - install according to the spice user manual item 6.1.2 (just
  grab the latest binaries from spice-space.org)
 fedora - yum install spice-vdagent
