[Users] 3.2 beta: how to add iscsi domain to a f18 host

Hello, having a fedora 18 system configured as a node and working with a local_storage DC/CLuster, I then created an iSCSI dc and cluster and moved there the host Then I configured a CentOS server as an iSCSI sw target. But in admin portal the host section remains greyed out and I can't proceed. I suspect I have to manually install/configure some prerequisites to have the host work as iSCSI initiator.... Is it true? What I have to do on host part (or engine part) if I have not a node iso but a standard fedora 18 system as hypervisor? Here what I see in new domain box: https://docs.google.com/file/d/0BwoPbcrMv8mvX281aWlMYUlzWXc/edit?usp=sharing Thanks, Gianluca
