Setting up four virtual machines (VMs) depends on the software you're using. Here’s a general guide using VirtualBox, which is free and widely used. If you're using VMware, Hyper-V, or another platform, the process is similar.
1. Install Virtualization Software
Download and install VirtualBox from
https://www.virtualbox.org/Enable virtualization in your BIOS/UEFI if it’s not already enabled (look for "VT-x" or "AMD-V" in BIOS settings).
2. Download an Operating System (OS)
Get an ISO file of the OS you want to install (e.g., Windows, Linux, etc.).
Popular choices:
Windows: Download from Microsoft's website.
Ubuntu/Linux: Get from
https://ubuntu.com/download.
3. Create the First Virtual Machine
Open VirtualBox and click "New".
Enter a name (e.g., “VM1”), choose the OS type (Windows/Linux), and click Next.
Allocate RAM (at least 2GB for light use, more if needed).
Select Create a virtual hard disk → Choose VDI → Dynamically allocated → Set at least 20GB.
Click Create.
4. Install the OS
Select your new VM and click Settings.
Go to Storage → Click on the empty disk → Choose a disk file → Select your ISO.
Click Start to boot the VM and install the OS.
5. Clone or Repeat for 4 VMs
To quickly set up four VMs:
Option 1: Clone the first VM (Right-click → Clone → Choose "Full Clone").
Option 2: Manually Repeat steps 3–4 for each VM.
6. Configure Networking (Optional)
By default, VMs use NAT for internet access.
If you need VMs to communicate, change to Bridged Adapter in Settings → Network.
7. Start and Use Your VMs
Start each VM one by one.
Adjust CPU, RAM, and storage as needed in Settings → System.
