Kas tegi virtuaalmasinate pilte ja kuidas seda tegi?

Virtual machine images are created for rapid deployment of pre-configured environments. This is usually done using virtualization tools such as VirtualBox, VMware, or cloud platforms.

The process of creating an image includes:

1. Installing and configuring the operating system and necessary software on the virtual machine.
2. Cleaning up temporary files and data to ensure the image is "clean".
3. Saving the state of the virtual machine as an image (snapshot) or exporting it to an image file (e.g., .ova, .vmdk).

Example using VirtualBox:

# Create a virtual machine
VBoxManage createvm --name "MyVM" --register
# Configure the VM, install OS manually
# After configuration, export the image
VBoxManage export MyVM -o MyVM.ova

Tools like Packer are also frequently used in DevOps to automate the creation of images.
