I have finally mapped most missing keycode in the fr-ca keymap... The keys that are not working are "dead_keys". Anyone knows how to manage dead key properly?
If you are using fr-ca keyboard layout (french canada) and having problem in KVM guest, add the following entries at the end of the file /usr/share/kvm/keymaps/fr-ca
All components of the system use fr-ca keymap (the pvehost, the kvm guest and the client that connects to the java VNC console).
Eacute 0x35 shift
colon 0x27 shift
greater 0x2b shift
apostrophe 0x33 shift
period 0x34 shift
Thanks again dietmar...
