Given a scenario, set up and use client2.2
side virtualization


Understanding Client-Side
Virtualization


Platform Virtualization

Platform virtualization is performed on a given

hardware platform by host software, which
creates a simulated computer environment, a
virtual machine (VM), for its guest software



Client-Side Virtualization Benefits


Provide backwardscompatibility with LOB
applications with OS
requirements



Agile testing platform (fast
refresh)



Businesses rely upon server
virtualization; here we're
concerned with client-side VMs


Hypervisor

Computer hardware, firmware, or software
that runs VMs. Type 1 are "bare metal"
hypervisors, and Type 2 are "hosted"

hypervisors


Desktop Hypervisors
Microsoft Hyper-V (Windows)
VMware Workstation (Windows)
VMware Fusion (OS X)


Desktop Hypervisors

Oracle VirtualBox VM (Win, OS X, Linux)
Parallels Desktop (OS X)


Assessing Virtualization
Requirements


Resource/Emulator Requirements


Remember that a VM
emulates the host hardware
in software
-



CPU

RAM
Storage
Network

VMs are limited by the host's
hardware


Network Requirements


Security Requirements


VMs need to be secured in the
same way as physical hosts
-



They are just as subject to
malicious code

VMs are ultimately represented
as file system objects
-

File encryption (BitLocker VHD
containers)

Creating and Managing
VMs


Demo:
Show my VMware environment
Connect to my Mac and show VMware
Fusion Unity mode

Homework



Create a two-VM virtual network
Configure each VM with two
virtual NICs:
-



bridged to host
host-only private network

Practice enabling and disabling the
virtual NICs


For Further Learning


Pluralsight: Introduction to Virtualization (David Davis)
-



David covers server virtualization, VMware, and the cloud

Pluralsight: Windows Server 2012 R2 (70-410) Configure Hyper-V

(Jason Helmick)
-

Great information on building virtual networks


Summary
Virtualization is a core skill set of
today's (and tomorrow's) system
administrator
Today's push is to host VMs in the
cloud
