Building my lab: oVirt iscsi multipath woes

In this video I go through setting up iscsi multipathing between oVirt 4.3 and FreeNAS 11.2. I was hoping to get it working as I had in the past, but it turns it it wasn't so easy and just didn't work. Though the efforts are hampered by a host with a corrupted disk. Oh joy.

This was so painful! What was I doing wrong here?
