Red Hat Enterprise Virtualization for Desktops
Red hAt enteRPRiSe viRtuAlizAtion hyPeRviSoR: viRtuAl deSktoPS
as described above, the Red Hat Enterprise Virtualization Hypervisor runs linux, kVm, a resource
optimization layer, and then the virtual desktops. the virtual desktops can be either microsoft windows
or Red Hat Enterprise linux desktops.
desktop optimization
the Red Hat Enterprise Virtualization Hypervisor runs a resource optimization layer that is tied very closely
to kVm and plays a role in improving the density of virtual desktops on the server, assisting in the remote
rendering of the virtual desktop, and enabling the Red Hat Enterprise Virtualization Hypervisor to be a part
of the Red Hat Enterprise Virtualization Hypervisor cluster.
the desktop optimization layer includes several industry-leading algorithms and mechanisms like memory
page sharing (done at the host level) or memory ballooning (done at the guest with host level interaction) to
improve the density of virtual desktops on a given Red Hat Enterprise Virtualization Hypervisor server.

KVM
kVm has several advantages over existing proprietary
and other open source virtualization solutions.
one of the primary reasons kVm is a superior
architecture is that kVm is part of the linux kernel.
Hence, all the improvements made by the vast open
source community around the linux scheduler,
memory management system, or other components
accrue naturally to the kVm virtualization platform.
previous generation virtualization solutions are
essentially proprietary operating systems
(a hypervisor is an operating system of operating
systems) and have to maintain their own os and
take on the burden of constantly improving this os.
these include the scheduling mechanism, memory
management, and hardware support to keep up with
the latest technology. this places other solutions at
a significant disadvantage relative to KVM.
