Virtualization Technology

• What is virtualization?
• Virtualization is an abstraction layer that
  decouples the physical hardware from the
  operating system thereby
• allowing multiple virtual machines, with
  heterogeneous operating systems to run in
  isolation, side-by-side on the same physical
  machine.
• Consolidating multiple physical servers to run in
  single platform (easy to manage).
• More reliable?Easy to restart a system by
  bringing another fresh copy of VM files
• Current solutions
• VMware virtual server / ESX server
• Microsoft virtual server

What is virtual server

Using VM

• A virtual machine is same as a physical box
  without software. Thus to use a virtual machine,
  it needs to run an operating system to support
  its applications.

5
Using VM

• First, in old-fashioned way, we install operating
  system, configure it, install application,
  install other tools, configure them, and then the
  application is ready to use.
• Another approach is to somehow capture the
  existing software including the operating system
  and all configuration details, and then transfer
  it to the virtual machine? This is called P2V in
  short.
• Usages
• It can be used to a copy of prototype as a set of
  files (compact storage.)
• Allow the actual hardware to be used by other
  projects

UltimateP2V

• One of many available P2V solutions.ltwhat are
  theygt
• Created by Qui Hong, Chris Huss and Mike
  Laverick.
• It uses "BartPE" (Bart Preinstalled Environment)
  to boot the physical and virtual machine, and
  then uses Symantecs ghost software to clone hard
  disk.

7
P2V transfer.

• Here are the steps, how I migrated physical linux
  machine (eca) to the virtual machine (starget1)
  on walrus.uccs.edu.
• Create UltimateP2V bootable CD/iso image.
• Create virtual machine (specify .)
• Boot both virtual as well as physical machines
  with UltimateP2V CD
• Clone the hard disk from physical machine. It
  utilizes the Norton ghost server software to
  transfer disk images.
• Boot virtual machine and configure OS for the
  hardware components present.

8
Creation of UltimateP2V

• Download UltimateP2V software from RTFM
  Educations website.
• The boot CD uses windows 2003 software.
• In addition, it needs VMware VMXnet network
  driver, LSILogic driver, VMware SCSI Buslogic
  driver, Qui Hongs Fix-VMSCSI FreeP2V plug-in,
  VMware tools and SVGA Graphics driver.

9
Creation of UltimateP2V Step1 Preparation.

• It uses Symantec Ghost software to clone hard
  disk.
• Since eca contained NIC card from 3COM, we
  needed 3COM NIC driver to be added into
  UltimateP2V image.
• Using pebuilder.exe, I created the iso image file
  and then burnt it on a CD.

Creation of virtual machine

• On walrus machine, VMwares virtual server is
  available. I created a virtual machine named
  starget1 in it, with one CPU, 384 MB of RAM and
  32 GB of virtual hard disk.

P2V process

• Booted physical and virtual machines with
  UltimateP2V disk.
• Started network support and configured network
  details like IP address, default gateway address
  and subnet mask.
• Started Ghost8 and set virtual machine in slave
  mode (as receiver to receive disk image) , and
  physical machine in master mode (as sender to
  send its disk content).

P2V continued.

• The master mode gives option to select source
  disk drive and destination drive.
• This transfers the details from physical machine
  to virtual machine.
• After the completion of cloning, the virtual
  machine is up and ready for use.

V2P process

• The UltimateP2V CD created is also capable of
  transferring virtual machines to physical
  machine, Virtual-to-Physical. I reversed the
  master and slave modes. The ghost8 on virtual
  machine is started in master mode and physical
  machine was started in slave mode.
• I performed V2P from starget1 to frodo machine
  successfully.
