Where's the guest application that drives the copy/paste? I expect the first problem you'll run into is that copy/paste daemon has to run as an unprivileged user but /dev/vmch3 is going to be owned by root. You could set udev rules for /dev/vmch3 but that's pretty terrible IMHO. I think you'll find that you need a root daemon that talks to vmchannel and then allows unprivileged connections over a unix socket device. In that case, why even bother having multiple channels since your daemon can multiplex.. Regards, Anthony Liguori
