Ways of using Open source/freeware

Windows based Portable apps (http://portableapps.com/)

Linux Based Multi-boot using Wubi (http://www.ubuntu.com/desktop/get-

ubuntu/windows-installer)

Multi-boot using different partition USB bootable Linux (U-thinker Project)

Running Linux in Windows AndLinux (http://www.andlinux.org/) Virtualization

Virtualization (From wikipedia)

Allows a single host computer to create and run one or more virtual envirnoments.

Virtualisation software is most often used to emulate a complete system in order to allow a guest OS to be run.

Benefits of using VM in computer subject

No ”extra” computer needed. Better hardware utilization. Several VM can be set up in a new PC.

The Guest OS is independent of Host OS. Suitable for access ”Dangerous site”

”Easier” to back up.

Faster installation.

Predictable Hardware behavior

6

Usage of Virtualization in Computer subjects

A platform to use of Linux based open source software.

Students can install and config OS using the Virtual machine.

Network Experiment can be done with several Virtual machines.

Practice of Configuration of server become easier.

Stored VM in USB drive for homework.

VM used in workshop

Hosted OS: Windows XP

Guest OS (VM): Ubuntu 10.10 Desktop, Ubuntu 10.10 Server (LAMP) Difference between Desktop and Server version

Beware of Licence issue of VM (guest OS) Microsoft licensing http://www.microsoft.com/licensin

Four Common Desktop Virtualization products

Xen (http://www.xen.org/) Host OS: Linux

Microsoft Virtual PC (http://www.microsoft.com/windows/virtual-pc/)

Host OS must be Windows

Support Limited distribution of Linux

Suitable for use of Trial VM downloaded from Microsoft

Four Common Desktop Virtualization products

Sun - Virtual Box (http://www.virtualbox.org/)

Host OS: Windows, Linux, Mac

Generation of new VM.

Configuration of VM.

Four Common Desktop Virtualization products

VM Ware (http://www.vmware.com/)

Virtual appliances (http://www.vmware.com/appliances/) on the web. Host OS: Linux, Windows, Linux, Mac. VMware player (Freeware)

Limited configuration options VMware workstation.(30 days trial) It includes

Vmware player Virtual Network Editor VMware Workstation License numbers (30 days)

11

Suggested Hardware

CPU: P4 or above

RAM: 1G or above

HardDisk space: 5GB or above

Preferred NTFS.

12

Generation of VM

VMware workstation Use the software to generate a new VM

VMWare player Go to http://www.easyvmx.com/new-easyvmx.shtml

Generate a configuration file

Practice 1 Preparation – download & install VMWare player

13

Switch between VM and Host

Direct Input to VM Click the VM's window

Press CTRL-G

To return to Host computer Move the Mouse outside the VM's window

Press Ctrl-Alt

VM hardware 2

Harddisk 8GB for the VM in workshop

CD: iso or physical drive Connect to Physical CD. It willl disconnect from Host

Connect to Disk Image file (iso)

Floppy Disk Connect to physical drive

Connect to Disk Image File (flp)

16

VM hardware 3

Network adapter Bridged

VM obtain an IP in the subnet of the host

NAT (VM config in Workshop)The host computer act as NAT

Host only (No external connection)

VM1 VM2

VM hardware 4

Sound Card

USB devices: When VM connected to a USB devices. It will disconnect from host.

For USB devices, DVD/CD, floppy. umount (  卸載檔案系統 ) the devi

ces

Then disconnect / Remove.

18

Run VM in USB drive

Practice 2: Generation of VM

- Using a 3rd party tool
