This chapter provides the information and steps for creating a guest virtual machine as well as starting, stopping, removal, and cloning it, and also some great features such as snapshot, clone, and VM groups.
On the VirtualBox Manager, click on the New button at the top and a wizard that will help to create the virtual machine will pop up.
The wizard will ask for some information based on the information provided by the user and the guest VM will then be created.
As shown in the following screenshot, provide the name of the VM; I have used the name OELVM. In the Type field, Linux should be selected. If you want some other OS to be the guest VM, then choose it from the list. In the Version field, choose Oracle and click on Next.
In the following screenshot, select the amount of memory. I have kept 2048 MB for Oracle Enterprise Linux. However, you may resize it after the installation. Click on the Next button.
The following screen will appear. Select the Create a virtual hard drive now radio button. Click on the Create button. It will create a new virtual hard drive.
Select VDI as shown in the following screenshot and click on Next:
You can choose either of the options; I have chosen Dynamically allocated. The difference between Dynamically allocated and Fixed size is self-explanatory.
Note
A dynamically allocated disk is initially small on the host hard disk, and it grows later depending on the data that is written to the virtual disk by the guest OS.
A fixed size disk will immediately occupy the entire size that is allocated, even if only a fraction of the virtual hard disk space is actually in use.
As shown in the following screenshot, click on Next:
Select the size of the disk for your VM; I have selected 12 GB considering that it's a test machine. If you need more space, please resize it accordingly. Click on the Create button.
It will take a bit of time to create the VirtualBox disk image (VDI). Then your virtual hard disk will be created.
If everything goes well, you can see the guest VM that you have created. In my case, it is OELVM.
