I thinks users often want to know what is virt-sysprep doing on his
guest, if silence, I don't know if the process is running or already
hang up. So, I also think that showing simple logging for users should
be made default.

Above all, I think keep silently when running for a bit long time is
not a good idea, do you think so?
