Explore virtualization basics: run multiple operating systems on a host, boost hardware utilization, and understand software, memory, storage, data, and network virtualization, with Oracle VirtualBox as a platform.
Explore virtualization vendors in the market and compare Oracle VirtualBox with ESXi solutions, understanding how each creates isolated virtual machines with an operating system, RAM, and storage.
Create your first virtual machine in VirtualBox by naming it, selecting a Linux 64-bit profile, and configuring RAM and a dynamically allocated 80 GB hard disk.
Download the CentOS 7 ISO file and install it on VirtualBox using ISO images instead of a CD drive, recognizing CentOS as open source.
Learn to install CentOS 7 on Oracle VirtualBox by attaching the ISO, booting the VM in GUI mode, and configuring language, software packages, partitioning, hostname, and root password.
Complete post-installation tasks in VirtualBox after Centaurus Linux is installed, including accepting the license information, setting language and time zone, creating a user, and launching the Centaurus desktop.
Assign an ip to the CentOS virtual machine in VirtualBox by matching its ip address parts with your Windows host, configuring subnet mask and gateway, and testing connectivity with ping.
Increase or decrease the virtual machine's RAM by shutting it down, opening VirtualBox settings, and using the system RAM slider, while leaving about 4–5 GB for the host Windows OS.
Add a new hard disk to a VirtualBox VM, allocate 100 gb, create a partition, format the filesystem, mount it to /apps, and update fstab for automatic mounting.
Learn to add a new network card to a VirtualBox VM, copy the MAC address, and configure the new interface with bridged networking and dynamic or manual IP addresses.
Learn how to use VirtualBox snapshots to save and restore a running virtual machine, including hard and regular snapshots, testing workflows, and rolling back after changes.
Learn to create a full VM clone in Oracle VirtualBox, reinitialize MAC addresses, select full clone, clone from state, and perform post-clone steps like changing host name and IP addresses.
Save the virtual machine state to suspend the guest and resume exactly where you left off; start the virtual machine later to continue from the saved point.
Export a virtual machine as an open virtualization format archive, then import the .ova file on another host. Clone via right-click clone, or export and import, with templates for deployment.
Copy files from a Windows host to a Linux virtual machine using a Windows transfer utility by connecting to the VM IP, logging in as root, then drag and drop.
Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and Innotek VirtualBox) is a free and open-source hypervisor for x86 computers currently being developed by Oracle Corporation. VirtualBox may be installed on a number of host operating systems, including: Linux, macOS, Windows, Solaris, and OpenSolaris.
