I did the following to install Ovirt:

Installed CentOS 7.  Then after install I ran the below commands:

sudo yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm

sudo yum update

sudo yum install ovirt-engine

sudo engine-setup

I did the default settings for setup.

I did this command to change the hostname:

sudo /usr/share/ovirt-engine/setup/bin/ovirt-engine-rename --newname=

I logged into the admin page and started creating a datacenter, cluster, and host.  I could never get the storage domain to add the iSCSI drives.  It kept saying it was in use when I was making sure it was disconnected in CentOS and connecting to it from the ovirt admin interface instead.  To resolve this issue I did the following:

I followed this walk through to connect to the drive.  I then used fdisk to delete all partitions and the boot record since they are not needed.

I follwed the steps here https://wiki.mageia.org/en/How_to_delete_a_partition_with_fdisk

After that I logged out of the iscsi drive then tried again to add a storage domain and it worked!!
