A host machine is a physical hardware that typically runs resources in order to host virtual machines. If the machine (or hypervisor) runs one or more virtual machines, this will constitute a host machine. The machines depending on said Hypervisor, are called guest machines.

A virtual machine is a guest machine that is hosted on a physical hardware system, known as a host machine. The physical hardware system runs a software program called a hypervisor, which allows multiple virtual machines to be run simultaneously on the same host machine.

Virtual machines are often used for server virtualization, where multiple virtual servers can be run on a single host machine. This allows for better utilization of hardware resources, as well as easier management of server deployments. Additionally, virtual machines can be used for desktop virtualization, where users can access their own virtual desktop environment from a remote location.

Overall, virtual machines offer a number of benefits over traditional physical hardware systems. They are more flexible and scalable and can be more easily managed and deployed. Additionally, virtual machines can be used to provide a level of isolation and security between different guest machines.
