Ubuntu, a dominant Linux distribution, is widely deployed as a virtual machine (VM) image due to its stability, security updates, and cloud integration. This paper examines the structure, acquisition, configuration, and optimization of Ubuntu VM images. It covers official sources (Ubuntu Cloud Images, Vagrant boxes), hypervisor compatibility (VMware, VirtualBox, KVM, Hyper-V), and key practices for resource management, guest additions, and system hardening.
