Working now :-)
Is this solution available on the wiki?

Hello all,
first post here :-)
When using VNC as the console to access the VM I can't use the
portuguese keyboard and see special characters. I tried it with VMs
running Fedora, CentOS and Debian.
If I ssh the VM, everything is correct on the terminal console.
Is this a issue from oVirt or from the VNC server running behind (I
guess it's the second).
Any help?

you can change the vnc keyboard layout via the config tool (VncKeyboardLayout option) globally.
still missing as a per vm option (though you can easily do this via a hook if you need it per vm)
