Client-Side Hypervisors

Victoria RussellISM 3013-3860766/28/2013

Hello. My name is Victoria Russell and this presentation is a brief overview about client-side hypervisors.1

What is a Hypervisor?A hypervisor is a hardware virtualization technique that operates on top of a single host computer.

CLIENT-SIDE HYPERVISORS

A hypervisor is a hardware virtualization technique that operates on top of a single host computer. It allows users to run several additional operating systems, which are referred to as guest operating systems on the host machine.2

Client-side hypervisors encapsulate all software of a desktop into a virtual machine and allow it to be run locally on any computer. CLIENT-SIDE HYPERVISORS

Client-side hypervisors encapsulate all software of a desktop -- OS, applications and data -- into a virtual machine, and allow it to be run locally on any computer, be it Mac, Windows or Linux. 3

This desktop virtualization technology also runs different versions of operating systems on the same machine. CLIENT-SIDE HYPERVISORS

Security and Quality of Service has been sited as two obstacles to client side hypervisors.

CLIENT-SIDE HYPERVISORSClient-side hypervisors can be classified as:Type 1 HypervisorType 2 Hypervisor

Client hypervisors can be classified as Type 1 hypervisor and Type 2 hypervisor.7

Type 1 hypervisors run directly on top of a computers hardware and become the computer's master control program.

CLIENT-SIDE HYPERVISORS

Type-1 hypervisor or bare-metal hypervisor run directly on top of a computer's host hardware. Type 1 hypervisors become the computer's master control program. These traditional virtual machine monitors (VMMs) create a separate subdivision (virtual machine) for each guest operating system.8

Type 2 hypervisors use the operating system already installed in the computer and create a runtime environment for the guest operating system.

CLIENT-SIDE HYPERVISORS

Type 2 hypervisors doesn't run directly on the host hardware but instead runs on a typical operating system that's installed on the host hardware. It uses the operating system already installed in the computer and create a runtime environment for the guest operating system.

CLIENT-SIDE HYPERVISORSPopular Client-Side Hypervisors Products Include:Citrix XenClientMicrosoft Client Hyper-VVMware WorkstationParallels Desktop 8 for Mac

Well known client-side hypervisors products include:Citrix XenClientMicrosoft Client Hyper-VVMware WorkstationParallels Desktop 8 for Mac10

Citrix XenClient

Citrix XenClient is a true Type-1 client hypervisor that lets users run multiple local virtual desktops simultaneously, side-by-side and in complete isolation. It is designed for enterprises and is available either standalone or through XenDesktop Enterprise and Platinum editions.

11

Citrix XenClientXenClient is available in three different editions:XenClient EnterpriseXenClient ExpressXenClient XT.

XenClient is available in three different editions: XenClient Enterprise, XenClient Express, and XenClient XT.

XenClient Enterprise is a desktop virtualization product composed of a client hypervisor, the XenClient Enterprise Engine, and a management server, the XenClient Enterprise Synchronizer. It includes features such as image management, patching and updating, backup and recovery, security and policy management, and PC migration. XenClient Express is the free edition of XenClient Enterprise which provides access to the XenClient Engine and a license to use the XenClient Synchronizer for up to 10 devices. It is designed for IT professionals, consultants, and small businesses.

XenClient XT has a special, hardened version of the XenClient Engine client hypervisor and hardware-assisted features for a high level of security. It is designed for the public sector and other industries with extreme security requirements.12

HOW CITRIX XENCLIENT WORKS

The XenClient solution is comprised of two technologies XenClient Engine and the XenClient Synchronizer.

XenClient Engine includes the client hypervisor and any virtual machines managed by the hypervisor.

The XenClient Synchronizer is the management server which manages multiple XenClient Engines. Users of XenClient Engine can download images from the XenClient Synchronizer and run them locally on their laptops or PCs. 13

Citrix XenClientGuest OS supported include:Windows XP, Vista, 7, 8Ubuntu 10.04, 12.10CentOS 4, 5Red Hat Enterprise Linux 4, 5, 6SUSE Linux Server 9, 10, 11Oracle Enterprise LinuxDebian Lenny and Squeeze

Microsoft CLIENT Hyper-V

Client Hyper-V is a Type-1 hypervisor.

Client Hyper-V is the virtualization technology built into Windows 8 previously available only in Windows Server. A similar functionality in Windows 7 is called Windows XP Mode.

Client Hyper-V enables you to run more than one 32-bit or 64-bit x86 operating system at the same time on the same host computer. But instead of working directly with the computers hardware, the operating systems run inside a virtual machine (VM). 15

Microsoft CLIENT Hyper-VGuest OS supported includes:Windows Server 2000 2008 R2Windows XP, Vista, 7, 8Linux (only including SUSE Linux Enterprise Server 10 with SP3 or version 11)Red Hat Enterprise Linux versions 5.2-6.1 CentOS 5.2-6.2

Hyper-V supports the creation of both 32-bit and 64-bit operating systems in virtual machines. You must license each of the virtual machine operating systems according to their requirements.16

VMware WORKSTATION

VMWare Workstation is a Type-2 hypervisor which takes advantage of the latest hardware to replicate server and desktop environments. It can create virtual machines with up to 8 virtual processors or 8 virtual cores, 2 TB virtual disks and up to 64 GB of memory per virtual machine to run the most demanding applications. 17

VMware WORKSTATION

VMWare Workstation runs applications on multiple operating systems including Linux, Windows and more at the same time on the same PC without rebooting. It can also support the creation of 32-bit and 64-bit virtual machines.18

VMware WORKSTATIONGuest OS supported include:Windows XP, Vista, 7UbuntuLinuxDebianCentOSNovell NetWareFreeBSDSun Solaris

Parallels desktop 8 for mac

Parallels Desktop for Mac is a Type-2 hypervisor which can run both Windows and Mac OS X applications side-by-side with speed, control and confidence. Drag and drop files between Windows and Mac applications and launch Windows applications from your Mac dock.

Parallels MOBILE APPYep! Theres an App for that!You can remotely access your Windows and Mac programs from your iPad or iPhone with our Parallels Mobile app.

You can remotely access your Windows and Mac programs from your iPad or iPhone with Parallels Mobile app. Parallels Mobile enables customers worldwide to seamlessly connect from their iPad or iPhone to the Windows applications available on their Mac. Parallels Mobile can start and stop Windows, so there is no need to keep Windows running.21

Guest OS supported include:Windows 3.11, 95, 98, XP, Vista, 7UbuntuLinuxDebianCentOSRed Hat EnterpriseSun SolarisMac OS X Leopard Server 10.5.xMac OS X Snow Leopard Server 10.6.xFreeBSDAndroid OSChrome OSMandriva 2011, 2010Fedora 17, 16, 15Parallels desktop 8 for mac

22

FUTURE OUTLOOKSome determining factors about the future of client side hypervisors include:The need for centralized desktop virtualizationThe increase in Cloud computingVirtualization that is hardware agnostic and independent of device and end-point

23

With these and other factors in mind, client side hypervisors continues to emerge as a viable solution for the future.
