Aline, the point is not the kdb_bus used to configure the keyboard, but the type.

Ramon, I guess you can update, on osinfo.py file, the common_spec dictionary to add the kdb_type value - this will be common to all cases. Then, you can add a new key into power specs specific to ppc64le that have this different value. Anyway, a little modification on vmtemplate.py will be necessary to use the new variable/key.

In osinfo.py we have a dict for each supported arch.

template_specs = {'x86': {'old': dict(common_spec, disk_bus='ide',
                                       nic_model='e1000',
sound_model='ich6'),
                           'modern': dict(common_spec, disk_bus='virtio',
nic_model='virtio',
sound_model='ich6')},
                   'power': {'old': dict(common_spec, disk_bus='scsi',
nic_model='spapr-vlan',
cdrom_bus='scsi',
                                         kbd_bus='usb', mouse_bus='usb',
                                         tablet_bus='usb', memory=1280),
                             'modern': dict(common_spec, disk_bus='virtio',
nic_model='virtio',
cdrom_bus='scsi', kbd_bus='usb',
                                            mouse_bus='usb',
tablet_bus='usb',
                                            memory=1280)}}

You should add the new ppc64le there with the right bus values.
So for ppc64el we should point the kbd_bus="keyboard"

And vmtemplate.py will not change.
