[virt-tools-list] virt-manager fails to fetch storage pool info and disconnects from server

[Thomas Fjellstrom]

I just reinstalled my server, and am attempting so create a couple new guests, 
but virt-manager will no longer connect to the server since I added the 
storage pools to the libvirtd config.

This is all I get after it prints out the server's description xml:

What would cause this?
