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
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!!
