[ovirt-users] Help!

Good evening Today it's been almost a week since my efforts are in vain in the face of this problem that pushes me to write to you again. I installed ovirt 4.3 on a minimal centos installation. Then I confided ovirt as well as the iso and data domains. Now the problem, I try to create a VM by setting up the entries and attaching a CD from the iso data center. As soon as I run the machine by opening the console, the VM blocks on the boot and the installation does not start. I'll give you two previews for my config and the problem in question. Thank you in advance to all those who would like to help me solve this problem.
