A host virtual machine (host HVM) is a virtual machine operated and hosted from a remote cloud server.
Host virtual machines are created and hosted entirely on a cloud service provider infrastructure and are available to remote users over the Internet under systematic access control, defined compute and I/O resources. Host virtual machines exhibit the same functionalities as those of a guest virtual machine but are accessed in a different way.
Host virtual machines are among the core virtualization techniques that enable users to create a virtual machine with a user operating system, applications and compute resources in most cases. The virtualization server manages the operation of all the host machines by assigning them static or dynamically scalable infrastructure resources, security and statistical information about their performance and throughput.
Host virtual machines request their compute power from the host server. The data they produce is also stored on the same or another virtualized storage environment, which is integrated with the virtualization manager application. The physical server hosting the virtual machines can have many different host virtual machines, each executing and operating together without affecting the operations of the others.
