I. Composition of virtualized desktops

Redhat Enterprise Virtualization desktop is an end-to-end desktop virtualization solution that provides all the required aspects for enterprises to deploy virtualized desktops. (Figure 1)

1. Red Hat Enterprise Virtualization hypervisor

High-performance and secure independent system management on Red Hat Enterprise Linux based on KVM (kernel-based Virtual Machine) TechnologyProgram. Red Hat Enterprise Virtualization hypervisor features,
It is an enterprise-class Linux 5.4 Based on Kernel-based Virtual Machine (KVM) and red hat. (Figure 2)

3. Spice (simple protocol for independent computing environments)

The adaptive remote submission Protocol provides the same end user experience as the physical desktop. Spice is an adaptive remote submission protocol used by Red Hat Enterprise Virtualization desktop edition to connect users to their virtual desktops. It contains three components:

Spice DRIVER: components that exist in each virtual desktop;

Spice device: component that exists in the Red Hat Enterprise Virtualization hypervisor;

Spice client: a component that exists on a terminal device. It can be a thin client or a dedicated PC used to access each virtual desktop.

These three components work collaboratively to determine the most efficient location for processing graphics, so as to maximize user experience and reduce system load. (Figure 3)

4. Integrated connection proxy

Web-based portals allow end users to log on to virtual desktops. This is a web-based portal, so users can access virtual desktops through thin clients or any private PC with Web browsers. After logging on to the portal, you can select the virtual desktop to be authorized to access.

Spice virtualization framework

For the first time, fedora 14 added the Red Hat virtual desktop architecture (VDI)-spice to the system. Meanwhile, fedora 14 became the first Linux release supported by spice.

Spice (simple Protocol Independent Computing Environment, simple protocol for Independent Computing
Environment is a desktop virtualization framework that provides enhanced remote desktop experience. It is also a desktop service presentation protocol, and Microsoft's RDP (Remote Desktop Protocol, remote
Desktop Protocol) and Citrix ICA (Independent Computing Architecture, Independent Computing
Architecture.

The spcie project is designed to provide high-quality remote desktop access, allowing usersServerRun multiple Linux or Windows clients through qemu and display the client on a remote computer. This option can only attract many home users and run multiple clients on a single server.Operating SystemAnd then display it on the remote client through the Virtual device interface, which will also attract many large organizations. Of course, spcie allows the fedora server to support remote desktop. The RHEL server also has this function, and each Remote Desktop runs on KVM.

Fedora 14 Operating System Desktop

Spcie allows users using fedora 14 to master the virtual desktop and allow remote users to log in from the Internet. In addition, spcie has features such as 2D acceleration, audio playback and recording, and encrypted connections.

Other important updates

The latest version of gnome 2.3.2 is used by default on the ora 14 desktop, and the kernel is Linux 2.6.35.6-45. fc14.i686. At the same time, we also found that fedora 14 supportsIntelIPMI (smart management platform Interface) remote service management software, on the other hand, allows the system administrator to more easily operate and manage remote hardware, and adds additional capabilities to connect to the LAN and identity authentication to guide the operation.
