Ways of using Open source/freeware

Windows based


Portable apps (http://portableapps.com/)
Linux Based

Multi-boot using Wubi (http://www.ubuntu.com/desktop/getubuntu/windows-installer)

Virtualization
3
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.
(http://en.wikipedia.org/wiki/Category:Virtualization_software)

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
5
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.
6
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)

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
12
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
13
VM hardware 1

Configuration Menu

Status Bar
14
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)
15
VM hardware 3

Network adapter

host
computer
VM1
VM2
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)
16
host
computer
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
devices

Then disconnect / Remove.
17
Run VM in USB drive
