4. BIOS
• BIOS (basic input/output system) – a program –
personal computer's microprocessor uses to get
the computer system started after you turn it on.
• Manages – data flow between the
computer’s OS and attached devices such as
the Hard Disk, Video adapter, I/O devices etc.
ADAD 4

5. Configure BIOS
• Before implementing virtualization – ensure
whether the hardware in your environment is
configured to support virtualization.
• If it is not configured we need to configure it in the
BIOS.
ADAD 5

6. Why Hardware Virtualization?
• Heart of virtualization – Hypervisor.
• The hypervisor directly interacts with the physical hardware
resources and emulates these resources to the virtual
machine guest OS.
• Without virtualization – operating system provides a
layered access to the resources called protection ring.
• Ring 0 – most privileged level – which can access the
hardware resource directly.
• Ring 1 – next level.
• OS – is in ring 0 and can access the resources and execute
application.

Why Hardware Virtualization?
• In virtualized environment – operating system can’t
sit in ring 0. Because
• Ring 0 – Hypervisor, and
• Ring 1 – Guest operating system.
• But the problem is some of the operating system
instruction will execute only if the OS is in ring 0.
• So in the virtualized environment – hypervisor
captures OS instructions and emulates – results in
performance degradation.

Why Hardware Virtualization?
Therefore,
• The hypervisor workload is more so we can run
only limited number virtual machines in the
physical server.
• If we run more number of virtual machines, the
users will not get the desired performance.
• To address these issues – Hardware Virtualization
Technology is introduced.
ADAD 8

9. Features – Hardware Virtualization
• Hardware Virtualization – makes the underlying
hardware aware of the virtualization so that the
workload of the hypervisor is reduced.
• If hardware assisted virtualization is enabled, then:
• Ring 1: Hypervisor, and
• Ring 0 – Operating system
• so that the hypervisor doesn’t have to emulate
anything, the guest operating system can directly
access the hardware.
• Result – we can run many virtual machines on the
physical server without any performance degradation.
• Conclusion – hardware assisted virtualization enhances
the performance of the virtual machine.

10. Configure the BIOS to Support Hardware
Virtualization
• Computers help in enabling hardware virtualization
that enhances the performances of virtual machine.
• Enabled by default – in MAC OS.
• Not available by default – in Windows operating
system.
• Before configuring the BIOS we will have to first check
whether the hardware assisted technology is already
enabled.
• There are the few steps which help us to check if
hardware virtualization is already enabled in Windows.
ADAD 10

11. Steps – to check if hardware virtualization is
already enabled in Windows
1. Download “havdetectiontool.exe” from
https://www.microsoft.com/en-
us/download/details%20.aspx?displaylang=en&id=592.
Double-click the file which you have just downloaded.
2. After that a message box will be appear like this: “Do you
want to run this file?” Click on Run.
3. Next you will get the message like this: “Do you want to
allow the following program to make changes to this
computer?” click Yes to proceed.
4. You may be presented with license terms, then check I
accept the license terms and then click Next.

6. A window with the following report is displayed:
6.1 “Hardware-assisted virtualization is not enabled on
this computer” click enable.
6.2 “This computer is configured with hardware-
assisted virtualization”, the hardware virtualization is
already enabled.
7. Finally Select “No, I don’t want to send data”, then click OK.
ADAD 12

13. Enabling – Hardware Virtualization
• The hardware virtualization – is not default.
• We can enable this by changing the BIOS setting of the
computer.
• It can be accessed immediately by turning on the computer
and hitting f1, f2, f10, f12, delete or esc.
• After the feature is enabled, we need to “apply" or "save”
the changes and then reboot the system.
ADAD 13

14. Steps to enable Virtualization in PC BIOS
1. First, reboot the computer and open the system's BIOS
menu. Computer can be rebooted by pressing the delete
key, F1 key or Alt and F4 keys depending on the system.
2. After that Select Restore Defaults or Restore Optimized
Defaults and then select Save & Exit.
3. Finally, power off the machine and disconnect the power
supply.
4. Enabling the virtualization technologies in BIOS.
Note: BIOS steps The steps below may differ based on your
motherboard, processor type, chipset and OEM (Original
Equipment Manufacturer).
ADAD 14

15. Contd..
We need to verify the system’s hardware documentation for
the detailed information, for configuring the system. (The
following steps are for Intel VT and AMD-V)
a) First Switch on the power of machine and open the BIOS as
instructed in Step 1.
b) After that, open the Processor sub menu, the processor
menu may be found in the Chipset, Advanced CPU
Configuration or Northbridge.
c) Select to Enable Intel Virtualization Technology which is also
known as Intel VT or AMD-V depending on the brand of the
processor. The virtualization technologies may be labelled
Virtualization Technologies, Vanderpool or various other
names depending on the OEM and system BIOS.
ADAD 15

16. Contd..
d) And then Enable Intel VT or AMD IOMMU or the
other technologies.
e) Finally, Select Save & Exit.
5. Before checking the status, Power off the machine
and disconnect the power supply.
6. The following command is executed and if the
output is generated it implies that the virtualization
technology is enabled successfully or else the system
does not have virtualization or the correct BIOS is not
enabled.

Windows Virtual PC
Implementing Virtualization Environment

18. Implementing virtualized environment – using
Virtual PC
• Virtual PC is a feature of Microsoft – allows us to
run virtual machine on top of the Windows 7
machine.
• Virtual PC is a type 2 hypervisor so it has to be
installed on the top of an operating system. It can
be installed on the Windows 7 OS.
• Once the Virtual PC is installed on the Windows 7
machine we can create and run many virtual
machines on the Windows 7 machine.
ADAD 18

19. Features of Virtual PC
• Create and run many virtual machines.
• Windows XP mode – using this feature we can run
the application (on Virtual machine) which is
supported by XP but not compatible with the
Windows 7.
• Microsoft Virtual PC – freeware.

Implementing virtualized environment – using Virtual PC
• Initially we need to download and install the 32-bit
(x86) or 64-bit (x64) version of Windows Virtual PC
for your 32-bit or 64-bit Windows 7 for the system.
• System Requirements for Windows Virtual PC:
• The 1 GHz 32-bit / 64-bit processor which has to
support Intel Virtualization Technology.
• 2 GB RAM is recommended.
• The minimum hard disk space per virtual
Windows environment is 15 GB.

• System Requirements for Windows Virtual PC:
• The operating systems that has to be installed in the
system are :
1. Windows 7 Home Premium (32-bit or 64-bit)
2. Windows 7 Professional (32-bit or 64-bit)
3. Windows 7 Ultimate (32-bit or 64-bit)
