Virtual technology refers to creating virtual versions of computer hardware, operating systems, and other resources. Types of virtualization include server, application, presentation, network, and storage virtualization. Microsoft Hyper-V is a native hypervisor that can create virtual machines on Windows systems. To use Hyper-V, you install it in Windows features, open the Hyper-V Manager, configure networking like virtual switches, and create and install guest operating systems in new virtual machines.

3. WHAT IS VIRTUAL TECHNOLOGY?
• In computing, virtualization refers to the act of creating a virtual (rather
than actual) version of something, including virtual computer hardware
platforms, operating systems, storage devices, and computer network
resources.

4. TYPES OF VIRTUALIZATION
1) Server Virtualization – consolidating multiple physical servers into virtual servers that run on a single physical server.
2) Application Virtualization – an application runs on another host from where it is installed in a variety of ways. It
could be done by application streaming, desktop virtualization or VDI, or a VM package (like VMware ACE creates
with a player). Microsoft SoftGrid is an example of Application virtualization.
3) Presentation Virtualization – This is what Citrix Met frame (and the ICA protocol) as well as Microsoft Terminal
Services (and RDP) are able to create. With presentation virtualization, an application actually runs on another host
and all that you see on the client is the screen from where it is run.
4) Network Virtualization – with network virtualization, the network is “carved up” and can be used for multiple
purposes such as running a protocol analyzer inside an Ethernet switch. Components of a virtual network could
include NICs, switches, VLANs, network storage devices, virtual network containers, and network media.
5) Storage Virtualization – with storage virtualization, the disk/data storage for your data is consolidated to and
managed by a virtual storage system. The servers connected to the storage system aren’t aware of where the data
really is. Storage virtualization is sometimes described as “abstracting the logical storage from the physical storage.

5. HYPER-V
• Microsoft Hyper-V, codenamed Viridian and formerly known as Windows Server Virtualization, is a
native hypervisor; it can create virtual machines on x86-64 systems running Windows.

6. PREREQUISITES
Before you install Hyper-V, make sure that you have the following:
• A user account with administrator permissions for the computer.
• Enough memory to run all the virtual machines that you plan to run at the same time.
• Software to install as the guest operating system for the virtual machine.
INSTALL HYPER-V AND CREATE A VIRTUAL MACHINE

7. INSTALL HYPER-V
• Hyper-V isn’t installed by default on Windows 8 or 10 Professional and Enterprise systems, so you’ll
have to install it before you can use it. Thankfully, you don’t need a Windows disc to install it — you just
need to click a few checkboxes.
• Tap the Windows key, type “Windows features” to perform a search, and then click the “Turn Windows
features on or off” shortcut. Check the Hyper-V checkbox in the list and click OK to install it. Restart
your computer when prompted.

9. OPEN HYPER-V MANAGER
• To actually use Hyper-V, you’ll need to launch the Hyper-V Manager application. You’ll find it in your list
of installed programs, and you can also launch it by searching for Hyper-V.
• The Hyper-V Manager application refers to a “virtualization server,” which gives away its heritage as a
tool for servers. It can be used to run virtual machines on your own computer — in that case, your local
computer functions as a local virtualization server.

11. SET UP NETWORKING
• Click the name of your local computer in Hyper-V Manager to find the options for your current
computer.
• You’ll probably want to give the virtual machine access to the Internet and local network, so you’ll need
to create a virtual switch. Click the Virtual Switch Manager link first.

13. Select External in the list to give virtual machines access to the external network, and click Create Virtual Switch.

14. Give the virtual switch a name afterward and click OK. The default options should be fine here, although you should ensure
the External network connection is correct. Be sure to select the network adapter that’s actually connected to the Internet,
whether it’s Wi-Fi or wired Ethernet.

15. CREATE A VIRTUAL MACHINE
Click New > Virtual Machine in the Actions pane to create a new virtual machine.

16. The New Virtual Machine Wizard window will appear. Use the options to name your virtual machine and configure its basic
hardware. This should all be fairly self-explanatory if you’ve ever used another virtual machine program before. When you
reach the Configure Networking pane, you’ll need to select the virtual switch you configured earlier — if you didn’t configure
one, the only option you’ll see here is “Not Connected,” which means your virtual machine won’t be connected to the
network unless you add a network adapter to its virtual hardware later.

17. If you have an ISO file containing your guest operating system’s installation files, you can select it at the end of the process.
Hyper-V will insert the ISO file into the virtual machine’s virtual disc drive so you can boot it afterwards and immediately start
installing your guest operating system of choice.

18. BOOT THE VIRTUAL MACHINE
• Your new virtual machine will appear in the Hyper-V Manager list. Select it and “Start” it — click Start in
the sidebar, click Action > Start, or right-click it and select Start. The virtual machine will boot up.

19. • Next, right-click the virtual machine and click Connect to connect to it. Your virtual machine will then open in a
window on your desktop — if you don’t connect to it, it just runs in the background with no visible interface. Again,
it’s easy to see how this management interface was designed for servers.
• After you connect, you’ll see a standard virtual machine window with options you can use to control the virtual
machine. It should look familiar if you’ve ever used Virtual Box or VMware Player. Go through the normal
installation process to install the guest operating system in the virtual machine.
• When you’re done installing the operating system, click Action > Insert Integration Services Setup Disk. Open the
Windows file manager and install the integration services from the virtual disc.

21. • When you’re done with the virtual machine, make sure you’ve shut it down or turned it off in the Hyper-V Manager
window — just closing the window won’t actually close the virtual machine, so it will stay running in the background. The
virtual machine’s state should be “Off” if you don’t want it running.

22. • Hyper-V has other useful features, too. For example, checkpoints
work like snapshots in Virtual Box or VMware. You can create a
checkpoint and then revert your guest operating system’s state to
that state later. It’s a useful feature for experimenting with software
or tweaks that may cause problems in your guest operating system.
