But when I view the VNC console..It shows nothing but a Black Window. And I see none remarkable error @ tail -f /var/log/ovirt/ovirt-engine/engine.log Only the following things: * "No one is waiting for resource 'Storage.fce396f2-72cb-11e2-acc2-000c29a7b590"* In fact I have been hanging in this place for 3 to 4 days.
