There are several virtualization software available for Linux ie: VirtualBox, VMware, KVM and maybe some others. In this short tutorial, I will show you how to create a new virtual machine using Virtual Machine Manager in Ubuntu 11.04. You can install this Virtual Machine Manager via Ubuntu Software Center easily. With this application you can have another Operating System running on top of your Linux system.
Step 1. Open Virtual Machine Manager
Step 2. Click New Virtual Machine. Then a new wizard will be opened.
Enter your virtual machine name, and choose how you would like to install the OS. In this case, we use local install media (ISO image or CDROM). Press Forward
Step 3. Browse to the ISO file location. Use the browse local button instead.
Choose an operating system type and version from the list and press Forward.
Step 4. On the next page, you need to specify how much memory and cpu allocated to the new virtual machine.
Step 5. Allocate how much hard disk for the new virtual machine
Step 6. Now you are ready to boot up your new virtual machine. Review the virtual machine summary before you start powering it up.
Now press finish to boot to your new virtual machine.
