I hit a lot of errors when I tried to upload through the web UI. I tried both remote URI and local file and both failed for me. I cant remember exactly what they were but I recall its where I spent a lot of time initially. I think it had something to do with the ovirt-imageio function...something around that I couldnt get working right. Also, doing the way I did it allowed me to quickly restart if I needed to by creating an alias around dd command. I had to restart a bunch so it was useful. I did this all onĀ 4.0.1.1-1.el7.centos
