yesterday i tryed to use kvm to manage some of my virtual machines and i also tryed spice as remote control instead vnc. Spice is great

i only need to install some packages in guest os and add a channel in virt-manager.
My problem now is how use clipboard (copy and paste). Seems that spice support it using spice-vdagentd in guest and host os. So i builded and installed on my Mga4 and in my guest os and spicy (spice gtk client) say my "agent:yes" so two agents should work but when i try to copy and past between 2 os, i have nothing.
Could you help me ?
thanks
