Red Hat Enterprise Virtualisation is a complete open-source virtualisation solution, derived from the Red Hat Enterprise Linux kernel, Kernel-based Virtual Machine (KVM) technology and oVirt virtualisation management projects.
Red Hat Virtualization is an enterprise-grade server and desktop virtualisation platform built on Red Hat Enterprise Linux. There are three core components to a Red Hat Virtualization environment:
- Red Hat Virtualization Manager: A server that manages and provides access to the resources in the environment. This server can be a physical machine or a virtual machine. Moreover, the Manager can be set up as a virtual machine on a host in an environment that the Manager itself manages. This setup is known as a self-hosted engine setup.
- Storage: Storage is used to store the data associated with virtual machines in the environment such as the virtual machines themselves and ISO files that can be used to install operating systems or other software on those virtual machines. Storage can be implemented on several storage types, including NFS, iSCSI, GlusterFS and Fibre Channel.
- Hosts: Hosts are servers that provide the processing capabilities and memory resources used to run virtual machines. In Red Hat Virtualization, servers running Red Hat Enterprise Linux 6 or Red Hat Enterprise Linux 7 or a minimal operating system specifically designed to operate as a host in Red Hat Virtualization environments known as the Red Hat Virtualization Host can be used as hosts.
- Next Generation Hypervisor: With the next-generation hypervisor, Red Hat Virtualization 4 introduces a powerful and small footprint hypervisor, co-engineered with Red Hat Enterprise Linux, that behaves like an appliance structure, simplifying operations and the installation of packages and driver updates. Other benefits include the ability to quickly deploy modern technologies, easy customisation, better hardware support and configuration management integration
- Advanced network functionality: With an external network partner application programming interface (API), Red Hat Virtualization 4 simplifies the process of adding and supporting third-party network providers and lets you centralise your network management systems through Red Hat Virtualization Manager. This release also supports Red Hat OpenStack Platform Neutron OVS, which helps streamline shared services and minimise operations by deploying services across traditional and cloud-enabled networks
A New Advanced System Dashboard: Red Hat Virtualization 4 includes a new, advanced system dashboard that gives you quick access to detailed information about the use of CPU, memory and storage host resources for seamless management
- Support for RHEL Atomic Host: Red Hat Virtualization 4 provides support for Red Hat Enterprise Linux Atomic Host, allowing configuration of a guest system through RHV and the user portal and guest agents to be run as containers on the Atomic Host VM
- Upload Images with Image Uploader: The storage image uploader gives you a browser-based way to upload image files from either your local machine or a remote URL—no need for disparate third-party tools
- Make Infrastructure Changes by Yourself: And advanced migration policies let you make infrastructure changes in configuration values by yourself, which speeds up operations and performance.
