It looks like it has something to do with windows sharing on my storage appliance. When I enable CIFS, that hidden folder appears. The storage pool can't be created because the permissions on the .$EXTEND folder cannot be changed. Apparently for the pool to be created virt-manager needs full access to all files and folders.

moving to libvirt-users What is the .$EXTEND file? Is it a socket or something strange like that? - Cole
