A hypervisor is a software that allows multiple operating systems to run on one or more computers. This software is used in conjunction with virtual machines, which are programs that run on a computer as if they were their own separate computer. The hypervisor allows the virtual machine to use the resources of the host computer, such as the CPU and memory, without affecting the normal operation of the host computer. ..
VirtualBox is a free and open source software application for creating and managing virtual machines. It was initially developed by Sun Microsystems, but was later acquired by Oracle Corporation. VirtualBox can be used to create both Windows and Linux virtual machines. ..
Steps to Create a Linux Virtual Machine with VirtualBox
Download and install Ubuntu
Ubuntu is a popular Linux distribution that is easy to use and effective for cloud, Internet of Things, and other applications.
Ubuntu builds one Linux virtual machine on your computer depending on its architecture. If it’s a 64-bit computer, Ubuntu can use more resources, but if it’s a 32-bit computer, Ubuntu can use the same resources as a 32-bit computer. Choose the architecture that best suits your needs.
Install VirtualBox
You can use virtualization software such as VirtualBox to run a virtual machine on a physical computer. This free software has many benefits, including the ability to run the virtual machine without having to reinstall the operating system. Along with these benefits, you can expect strong community support and a wealth of productivity tools. VirtualBox works on all contemporary systems as well as a premium alternative like VMware. ..
Oracle VM VirtualBox Extension Pack and VirtualBox can be used together to create a virtual machine that can run any Oracle software. You can follow the installation instructions and choose default options when prompted. If you have firewall and antivirus software permission, you can also run VirtualBox.
Create a virtual machine
Step 2: In VirtualBox, click on the “File” menu and select “Open Virtual Machine.” Step 3: In the “Virtual Machine” window, click on the “Create” button. Step 4: In the “Name” field, enter a name for your new virtual machine. Step 5: In the “Description” field, provide a brief description of your virtual machine. Step 6: Click on the “Create” button to create your new virtual machine.
Step 2: After following these instructions, name your virtual machine according to a corporate naming convention. ..
Step 3: Then select Linux in type and Ubuntu in the version drop-down lists. Remember to select 32 bit or 64 bitbased on what you downloaded.
Step 4: Naming the virtual machine vaguely isn’t great, but it can be improved. Set a naming standard first!
VirtualBox will prompt you to select the memory you want to provide for your VM. This can be a little tricky. Make sure you add enough memory to your VM and at the same time leave enough for your host OS🇧🇷 If you have many VMs, allocate only the minimum necessary to run each one first. You can scale up as needed later, once you know the overhead of your resources. ..
Create a virtual hard disk for your VM. Choose how much hard disk space your VM needs and choose accordingly. Often the minimum requirement is between 8 GB to 15 GB.
Step 7: Then select the VirtualBox Disk Image (VDI) as the hard disk type.
There are a variety of hard drive types to choose from, depending on your needs. If you’re looking for a high-capacity drive, we recommend choosing an SSD as your hard drive type. If you’re only interested in data storage and don’t need the speed or capacity of a hard drive, we recommend choosing a HDD.
Start the virtual machine
Step 2: After the VM is up and running, you can use the following commands to explore it:
ls -l /usr/local/bin
-rw-r–r– 1 root root 5 Aug 9 17:12 /usr/local/bin
On the first screen, select the two checkboxes and click Continue🇧🇷 On the next screen, select the “Erase the disk and install Ubuntu” option. This will just erase the contents of the virtual hard disk you created earlier and it will not affect the host OS. click on the install now button in the lower right corner.
- Choose your localization and keyboard layout in the next two steps.
- Finally, give your VM a name and password.
After you create a new VM, you will need to enter the password you created to have all changes propagated. Once your VM restarts, enter the password to continue using your VM.
Final Words
Creating a Linux virtual machine with VirtualBox is possible by using multiple virtual environments on a single machine. This is done by using virtualization technology. The hardware is managed by the hypervisor, which also divides the physical resources of the virtual environments. Physical environment resources are partitioned to VMs as needed. The hypervisor schedules a request to physical system resources when the virtual machine is running and a user or program requests additional resources from the physical environment so that the operating system and virtual machine applications can access the shared pool of physical resources.
