Similarly, a host VM may exist as part of the resources of a single physical machine or as smaller parts of the resources of multiple physical machines.Ī virtual machine monitor (VMM), or hypervisor, intermediates between the host and guest VM. It can also be moved between host servers to accommodate demand fluctuations or use resources more efficiently. Thus, one or more virtual guest machines can run on a physical host machine. The host VM is the physical machine that provides the guest VM with computing hardware resources, such as:Ī guest VM can exist on a single physical machine but is usually distributed across multiple hosts for load balancing.

It is also known as a guest computer, guest OS or, simply, guest. The guest VM is an independent instance of an OS and associated software and information. However, the host VM is accessed differently from a guest VM. Its functionalities are similar to those of a guest VM. The host VM is hosted and operated from a remote cloud server. The host VM and guest VM are the two components of a VM. The virtualization server does these assignments to manage the operation of all host machines. It is also assigned security and statistical information about their performance and throughput. Its data is stored in a virtualization environment that is integrated with the virtualization manager application.Įvery host machine is assigned infrastructure resources that are statically or dynamically scalable. The host VM requests its compute power from the host server. Simply put, the host machine is the machine creating the guest VM. It allows users to create a guest VM with a user operating system ( OS), applications, compute resources, etc. The host virtual machine explainedĪ host VM is an important virtualization technique.

Together, the host virtual machine and guest virtual machine make up a virtual machine server.

A host virtual machine is the server component of a virtual machine ( VM), the underlying hardware that provides computing resources to support a particular guest virtual machine (guest VM).
