20.1. Virtual Machine Manager Architecture
Red Hat Virtualization is a collection of software components that work together to host and manage virtual machines. The Virtual Machine Manager (VMM) gives you a graphical view of the virtual machines on your system. You can use VMM to define both para-virtual and full virtual machines. Using Virtual Machine Manager, you can perform any number of virtualization management tasks including assigning memory, assigning virtual CPUs, monitoring operational performance, and save, restore, pause, resume, and shutdown virtual systems. It also allows you to access the textual and graphical console. Red Hat Virtualization abstracts CPU and memory resources from the underlying hardware and network configurations. This enables processing resources to be pooled and dynamically assigned to applications and service requests. Chip-level virtualization enables operating systems with Intel VT and AMD-V hardware to run on hypervisors.
