Virtual Machines for Testing and Development

1
Virtual Machines for Testing and Development

• What is a virtual machine (VM)
• Networked VMs
• Deploying applications

2
What is a Virtual Machine

• A Virtual Machine is a tricked OS that thinks
  it owns the hardware.
• Supported OSs include XP, 2003 Server Family,
  2000 Family, Linux, OS2, OS9
• VMs live inside a host OS, but are not aware of
  Host OSs existence.
• Host OS commonly selected is XP.
• Can run under 2000

3
Networked VMs

• Multiple VMs can run on a single Host OS
• VMs can be networked together in their own (non
  routable) class c network space
• An entire Microsoft domain can exist virtually,
  networked virtually, with out interfering with
  physical network

2003 Server with Exchange
2003 Domain Controller DNS/DHCP Server
2003 Server with SQL 2000 And IIS
Virtual Hub
2003 Server with Internet Security
Acceleration Server (Tri-Homed)
XP Professional (test client)
Loop-back for virtual domain network access
by Host OS only 192.168.1.1
XP Professional
Allow intermittent connection via 3rd Virtual
ISA NIC to physical Network so development
network can get patches. Optional.
Physical Network

Requirements For Using Virtual Machines

• MSDN Universal Subscription provides licenses to
  all development tools and servers platforms.
  (https//microsoft.na.subservices.com/msdn/contact
  .asp)
• VPC (Virtual PC, included with MSDN subscription)
• 2 gig of memory
• VMs memory is non-swappable
• VMs memory is unavailable to host
• Each server platform uses gt200meg RAM
• Leave enough RAM for host development tools
• 20 gig of hard drive space

6
Limitations of VPC

• Virtual Machines can only run on console
• Virtual Machines can only use one processor
• Virtual Machines cannot share a Quorum, therefore
  clustering is not supported
• VPC is only for Test and Development
• For Production
• VmWare (available now)
• Virtual Server 2005 (beta)

7
Virtual PC Console

• Launch VPC
• Briefly show each of the VM

8
Launch VM and Copy Some Files

• Launch the Domain Controller
• Demonstrate how easy it is to copy files between
  machines
• No file Shares
• No FTP

9
Mounting Media and VM Window Icons

• Mount CD/DVD ISO files
• Mount Physical CD/DVD
• Explain VM window Icons

10
Testing Application Deployment with our Virtual
Domain

• Validate our Enterprise deployment and
  installation of our application
• Test to make sure installation target machines
  are not adversely affected by our deployment
• Did DLL deployment damage target?
• Did we corrupt any registry entries
• Did we adversely affect any functionality on the
  installation target
• If we did damage our Virtual machine, no problem.
  Just copy source safe-d virtual hard drive file
  over the damaged hard drive file. Fix the
  problem and retest

11
VPN into Virtual Domain

• Why do we need a VPN?
• Our host development tools require access to
  virtual resources like SQL server
• Additionally, we can do file shares in a way
  that our development tools expect
• VPN is invisible to physical network since we are
  using a loopback adaptor as the NIC
• We can publish content to IIS both inside and
  outside of the VPN. But most content requires
  access to SQL resources, some content may need
  access to Exchange. Access to these servers is
  important during debugging.
• The host machine can maintain connection with
  outside network while we are debugging through
  VPN connection.

12
Deploy the Adventure Works Report Services
Example onto the Virtual Domains web server

• Use Visual Studio .net and build the application
• Deploy the application with Visual Studio .net to
  the web server

13
Create Simple Domain Login Script For Users

• Use virtual domain to create a login script for
  users
• Login script will map a drive (we will need in
  next example)

14
Develop and Deploy Exchange Organizational Forms
to the Domain

• An e-form is a form that can be sent to other
  users, via email but an e-form can contain
  graphical controls, and programming code.
• Exchange Organizational e-forms have domain
  visibility.
• The virtual domain allows developers to code,
  deploy and test organizational e-forms.
