How Virtual machine works?
We explained in detail how virtual machine works,
How virtual machine works? Virtualization is the process of building a software-based, or “virtual,” version of a computer with dedicated resources from a physical host computer, such as your personal computer, and/or a a distant server, such one located in the datacenter of a cloud service provider. A virtual machine is a computer file, often known as an image, that functions like a real computer.
It can operate in a window as a separate computing environment, frequently to run a different operating system—or even to serve as the user’s whole computer experience, as is typical on many people’s works on computers. Because the virtual machine is partitioned off from the rest of the system, the software within a VM cannot interfere with the host computer’s main operating system.
An operating system and an application are packaged along with information about the CPU, memory, storage, networking, and other computing resources that are required to run them in a virtual machine. A program known as a hypervisor examines the description before supplying the needed compute resources when this virtual machine is installed on a host computer.
On the same host computer, many virtual machines—even ones with various operating systems—can operate independently and concurrently.
Virtual machine-based systems are created to increase a host’s effectiveness. The system’s fine-grained resource parsing gives it extensive insight into systems. Additionally, these platforms give app-specific insights regarding costs, performance, resource usage, and development procedures. This is how virtual machine works information covers.
How to create virtual machine
To create a virtual machine (VM), you would typically follow these general steps: This is how to create a virtual machine
- Step1: Choose a Virtualization Platform: Select a virtualization platform that suits your needs. Popular options include VMware Workstation, Oracle VM VirtualBox, Microsoft Hyper-V, and KVM (Kernel-based Virtual Machine).
- Step2: Install the Virtualization Software: Download and install the chosen virtualization software on your host machine. Ensure that your system meets the hardware and software requirements for running virtual machines.
- Step3: Obtain the Operating System Image: Acquire the installation media or disk image of the operating system you wish to install on the virtual machine. This can be an ISO file, installation disc, or an image provided by the OS vendor.
- Step4: Create a New Virtual Machine: Open the virtualization software and create a new virtual machine. You’ll be prompted to provide details such as the virtual machine name, operating system type and version, allocated resources (CPU, memory, disk space), and network settings.
- Step5: Configure Virtual Machine Settings: Once the virtual machine is created, you can modify its settings according to your requirements. This includes adjusting the number of CPUs, memory allocation, storage settings, network configuration, and any additional options specific to the virtualization platform.
- Step6: Install the Guest Operating System: Mount the operating system installation media or specify the ISO file as the installation source for the virtual machine. Start the virtual machine and proceed with the guest operating system installation as you would on a physical machine.
- Step7: Customize Virtual Machine Settings: After the guest operating system is installed, you can further customize the virtual machine settings, such as installing virtual machine tools or guest additions for enhanced integration and performance.
- Step8: Manage and Use the Virtual Machine: With the virtual machine created and configured, you can now power it on and start using it. Install applications, perform updates, and set up the virtual machine as needed for your specific use case.
It’s important to note that the exact steps and options may vary depending on the virtualization software you’re using. The above steps provide a general overview of the process to create a virtual machine. Consult the documentation or user guides of the specific virtualization software for detailed instructions tailored to that platform.
Uses of Virtual Machine
Virtual machines (VMs) have a wide range of uses across various domains. Here are some common use cases for virtual machines:
- Server Consolidation: Virtual machines enable organizations to consolidate multiple physical servers onto a single physical machine. This helps optimize resource utilization, reduce hardware costs, and streamline server management.
- Development and Testing: VMs provide developers with isolated and reproducible environments for software development and testing. They allow for easy setup, configuration, and testing of applications across different operating systems and environments.
- Software Compatibility: Virtual machines allow running multiple operating systems on a single machine. This is useful for running software applications that may be designed for specific operating systems or require different software configurations.
- Legacy Application Support: VMs are commonly used to host legacy applications that may not be compatible with modern hardware or operating systems. Virtualization allows organizations to continue using older applications without the need for dedicated legacy hardware.
- Disaster Recovery and High Availability: Virtual machines play a crucial role in disaster recovery strategies. By replicating VMs to off-site locations or utilizing cloud infrastructure, organizations can quickly recover services and data in the event of a disaster or system failure.
- Desktop Virtualization: Virtual desktop infrastructure (VDI) leverages VMs to deliver virtualized desktop environments to end-users. This allows for centralized management, improved security, and access to desktops from various devices and locations.
- Training and Education: VMs are widely used in educational settings to provide students with hands-on experience in various software, operating systems, and networking concepts. They offer a safe and controlled environment for learning and experimentation.
