How to create virtual host with "Batch Create" plugin ?

I use Batch Create plugin.
My supersite is wpmu0.localhost.com.
I need to create others sites for domain names like :
wpmu3.localhost.com
wpmu4.localhost.com
Log file displays : Missing or invalid site address. What I missing ?
It's only works for :
wpmu0.localhost.com/wpmu3
wpmu0.localhost.com/wpmu4
