Subject: [PATCH] virt-xml: Start using --os-variant

From: Andrea Bolognani <abologna@redhat.com>

The option only works with --add-device for the time being,

so we prevent its use in all other cases.

It would be nice to have it work with --build-xml too, but

in that case the user would have to provide some extra

information that in the case of --add-device we can figure

out from the existing guest, and it's not entirely clear

whether that would even be that useful, so for now we're

not considering that case at all.
