Getting Started: Creating and Managing Your Virtual Machines

Virtual machines allow you to run multiple operating systems on a single computer or server. Whether you use a local hypervisor like VirtualBox or a cloud platform such as Azure, managing VMs efficiently improves performance and saves time.

Step 1: Prepare Your System
Enable hardware virtualization in BIOS or UEFI for smooth operation. Choose a hypervisor or cloud provider and download the operating system ISO you plan to install.

Step 2: Create the Virtual Machine
Launch your hypervisor or cloud portal and start creating a new VM. Name your VM, allocate resources like CPU, RAM, and disk space, configure the network, and attach a virtual hard disk.

Step 3: Install the Operating System
Attach the ISO and start the VM. Follow the on-screen prompts to install the OS. Install guest additions if using a local hypervisor for better performance and integration.

Step 4: Manage Your Virtual Machine
Power on or off the VM as needed, create snapshots to save its state, adjust resources, and monitor performance. Access the VM via console, RDP, or SSH depending on the OS.
