Sure. vncviewer has command line options for that, and you can also change it at runtime (F8 -> Options -> Input). Additionally I'd make that optional at qemu level, i.e. something along the lines of "-vnc $display,clipboard={on,off}" (details depending on the actual implementation of course). take care, Gerd
