Introduction to virtualization
Experience sharing in computer subject and IT management
Installation and configure of VM
Using open source in VM in computer subject
Server side application
Portable apps (http://portableapps.com/)
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
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.
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.
Predictable Hardware behavior
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.
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/licensing/
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
Sun - Virtual Box (http://www.virtualbox.org/)
Host OS: Windows, Linux, Mac
Generation of new VM.
Configuration of VM.
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
Virtual Network Editor
License numbers (30 days)
CPU: P4 or above
RAM: 1G or above
HardDisk space: 5GB or above
Use the software to generate a new VM
Go to http://www.easyvmx.com/new-easyvmx.shtml
Generate a configuration file
Preparation – download & install VMWare player
Direct Input to VM
Click the VM's window
To return to Host computer
Move the Mouse outside the VM's window
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)
Connect to physical drive
Connect to Disk Image File (flp)
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)
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.
Practice 2: Generation of VM
- Using a 3rd party tool
