Yes I saw VNC supports some of this; but consider a qemu started with -vnc and it's remotely displaying - I don't think we wire up VNC's copy/paste in qemu to give anything to the guest, because we've got nothing in the guest to present it as - which is what I was trying to add. > > Perhaps that way is just to standardise on the virtio-serial channel > > that spice already uses and provide that for other transports; > > but if not then it feels like there should be some standard. > > Not that easy I think, the channel is not used exclusively for > cut+paste but also some other, spice-specific stuff. > > We could try integrate this into qemu guest agent. > > Or use something completely separate. qemu guest agent works at system > level whereas cut+paste would work on user session level. spice solves > this by having both system and user daemon, where the user daemon talks > to the system daemon.

OK, I was less worried about the host stealing from the guest, since it normally already can.
