Glossary
Citrix XenServer A server virtualization platform that offers near bare-metal virtualization performance for virtualized
server and client operating systems. Citrix XenServer uses the Xen hypervisor to virtualize each
server on which it is installed, enabling each to host multiple Virtual Machines simultaneously
with guaranteed performance.

guest operating
system A distinct operating system instance running in a virtual machine.
host operating
system An operating system that is the foundation for a virtual machine.
hypervisor A hypervisor allows multiple operating systems to run concurrently on a host computer. Examples
of hypervisors are Citrix, VMware ESX, Hyper-V, and so on.
legacy operating
systems An older operating system, often incompatible with current hardware. Virtual machines permit a
legacy operating system to run on new hardware.
resource pool A resource pool is a collection of multiple similar XenEnterprise servers that are connected together
in a unified pool of resources. These connected servers share remote storage and common
networking connections. A resource pool enables for XenMotion (Live Migration) of virtual
machines, shared configurations, and automatic placement of virtual machines.

total estimated
transport volume The total volume, consisting of several disks and configuration files.
virtual machine
(VM) The emulation of a complete hardware system from processor to network card in a self contained,
isolated software environment, enabling the simultaneous operation of otherwise incompatible
systems.
virtualization A method of grouping computing resources together that allows them to be accessed in ways
that provide benefits over the original configuration. Virtualized resources generally improve
computing power and data storage.
VMware ESX
Server The VMware Red Hat Linux-based host operating system that provides a virtual machine solution.
