Hypervisor : The hypervisorsupports multiple VMsthat run a variety of guest operating systems by providing connectivity between the VMs and the network. The hypervisor for KVM is a host server with Red Hat Enterprise Linux (RHEL) installed. The earliest supported release for VM-FEX is RHEL 6.1, but some features (such as SR-IOV) require a later version.
The hypervisor must have a Cisco VIC adapter installed.

libvirt : Libvirt is an open source toolkit that allows you to manage various virtualization technologies such as KVM, Xen, and VMware ESX. Libvirt, which runs on the hypervisor as a service named libvirtd, provides a command-line interface (virsh) and provides the toolkit for a graphical user interface package (virt-manager).
Each virtual machine created and managed by libvirt is represented in the form of a domain XML file.

MacVTap : MacVTap is a Linux driver that allows the direct attachment of a VM's vNIC to a physical NIC on the host server.
VirtIO : The VirtIO paravirtualized network driver (virtio-net) runs in the guest operating system of the VM and provides a virtualization-aware emulated network interface to the VM.
