Each VM operates as if it were a standalone computer system, with its own CPU, memory, network interface, and storage, but all resources are shared from the physical host machine. Virtual machines are created using virtualization software that partitions the physical host machine's resources into multiple isolated environments. Each VM can run a different operating system, allowing for a variety of different applications and services to run on the same physical host machine. This allows for greater utilization of hardware resources, reduced power consumption, and improved flexibility and scalability compared to running multiple physical machines. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.console.zenlayer.com/glossary/v/virtual-machine.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
