[Users] vdsm configuration

Hello all, Can someone point me to some documentation regarding vdsm (and if needed libvirt) configuration? How it is accessed by the ovirt-engine and how to set it to a certain ovirt-engine on the network. Currently my libvirt is complaining that it can't work with ssh-less vdsm and I have no idea how to set up the keys for vdsm. Also I have no idea how to define the storage: in ovirt or in vdsm? Who is reporting the disks/files available? I hope I understood correctly that only the vdsm package is needed to make the physical machine available for ovirt and only ovirt-engine is doing all the heavy work. Also, if the questions are too "RTFM", please let me know where I can find any help related to ovirt. Best regards, Cristian Falcas
