Virtual machines (VMs) operate based on hardware-level virtualization, which means they emulate entire hardware systems, including CPUs, memory, and network interfaces, allowing multiple operating systems to run on a single physical machine. Each VM includes a full copy of an operating system, the application, necessary binaries, and libraries - taking up tens of GBs. VMs are completely isolated from the host OS, which is why they do not share the host OS. This is in contrast to containers, which share the host system's kernel and are more lightweight as they do not require a full OS within each container.
