Virt-Manager forces recreation of default storage pool?

[Jibun no Kage .]

Virt-Manager forces recreation of default storage pool?  Or is it 
libvirt that is forcing its existence?

I explicitly remove the default storage pool, never use it?  But every 
time I run virt-manager, the default storage pool magically reappears? 
How can I kill this thing persistently?

All my storage pools are on true, storage solutions, i.e. SAN, etc., not 
a local directory on each hypervisor, so frankly this default storage 
pool is useless, and confusing when it can't be removed.
