Virtualization

virtualization from wikipedia
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
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

usage of virtualization in computer subjects
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.

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

switch between vm and host
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

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)
