The complete command is: (in one line)
-device virtio-serial
-chardev spicevmc,id=vdagent,debug=0,name=vdagent
-device virtserialport,chardev=vdagent,name=com.redhat.spice.0

i.e. create a virtioserialport with a specific name (com.redhat.spice.0), and connect
it to a chardevice of type spicevmc and with name vdagent (the property is called name,
but it's actually the type of the spicevmc - so for instance there is another type for smartcard
channel usage called smartcard).
