VirtualBox : Creating a New Virtual Machine (VM)
This article provides an overview of creating a new virtual machine in VirtualBox (4.2).
On the console screen, click the "New" button on the toolbar.
Enter the name of the virtual machine, the type of the operating system and the specific verison of the operating system, then click the "Next" button. If you are using a 64-bit host OS, you can choose between 32-bit and 64-bit VMs. If you are using a 32-bit host OS, you can only use 32-bit guests.
Enter the amount of memory required by the VM and click the "Next" button. Remember to leave enough memory for the host OS to work properly. If you are running multiple VMs, try not to overallocate the memory or your host OS will start swapping like crazy.
Accept the option to create a new virtual hard drive by clicking the "Create" button.
Unless you have a specific file type requirement, accept the default VDI type by clicking the "Next" button.
Accept the dynamically allocated option by clicking the "Next" button.
If you don't want to use the defaults, enter the required location, name and size of the virtual disk and click the "Create" button.
On the resulting Console screen, click on the "System" section.
Amend the boot order, placing "Hard Disk" at the top and unchecking the "Floppy" option.
Click on the "Storage" section and click on the empty CD/DVD entry. In the attributes section, click the CD/DVD icon and select the ISO image you wish to use to install the OS, then click the "OK" button. Strictly speaking this is not necessary as you will be prompted for it on first boot.
With the VM highlighted, click the "Start" button.
The VM will boot into the OS installation, just like a regular machine. Proceed with the installation as usual.
In this case the VM was defined for an Oracle Linux 6 installation. You can see an example of this type of installation here.
