Nothing much really.  It is two ways to get to the same result.

Use a CentOS minimal OS install, plus the oVirt packages from the repository.

Or an oVirt Node ISO with all of the necessary package included.  Patchable and upgradable from the respective repositories.

Subject: [ovirt-users] what difference between enterprise Linux hosts and oVirt Nodes ?

Enterprise Linux hosts (Enterprise Linux hosts) and oVirt Nodes (image-based hypervisors) are the two supported types of host. Hosts use Kernel-based Virtual Machine (KVM) technology and provide resources used to run virtual machines.

But what difference between the Enterprise Linux Hosts and oVirt Nodes ? Please give me some explain in details,thanks!
