Simone already replied that you can already do that with loopback iscsi. That said, if you only want to manage a single host, with no plans for HA or grow, isn't virt-manager enough? Or even virsh, if you feel comfortable at the command line? > with local storage. logically there whould be no ha, but you can always use > it for kvm virtualisation and i think thats the main thing in ovirt. all > other with ha and external storage is good to have, but for smaller > situations or starting conditions to much to effort.
