[libvirt] how to configure keymap & keyboard layout with virt-manager

Hi, I'm fighting to configure the keyboard on libvirt (kvm) (0.6.1-0ubuntu5). I'm using a belgian keyboard, so, my question is : - Which keyboard layout should I place in the xml file (or through the vm display adapter configuration). - Which keyboard layout should I use in the vm ? PS: When I use 'be' as keymap on the vnc line, the libvirtd just segfault at startup. Regards, -- François Delpierre
