[libvirt PATCH 6/9] qemu: add dbus clipboard sharing

From: Marc-André Lureau <marcandre.lureau at redhat.com>
This feature requires to setup a "-chardev qemu-vdagent,clipboard=on".
"qemu-vdagent" is not a typical chardev that you can connect to another
end, so it doesn't map to a <serial> or <channel>. Set it up along with
"-display dbus" code instead.
