Basic Host Setup
Setting up the servers that host the VMs is pretty easy since oVirt takes care of installing required packages and setting up the firewall. So the main task is to install CentOS and setup networking and storage.
follow the following instructions on each node of the Ovirt Engine Cluster servers:
Install CentOS 7.2
Setting up the network is complex. We have 4 NICs available. We create two bonds containing 2 NICs each.
Bond0 is for WAN traffic, bond1 is used for oVirt management traffic and traffic by the VM networks.
We use VLANs for this purpose. In our setup we use a separate "client" and demilitarized zone.
