libvirt笔记 (1) —— 术语

以下内容摘自Libvert terminology and goals

a node is a single physical machine

an hypervisor is a layer of software allowing to virtualize a node in a set of virtual machines with possibly different configurations than the node itself

a domain is an instance of an operating system (or subsystem in the case of container virtualization) running on a virtualized machine provided by the hypervisor Hypervisor and domains running on a node

 

node

Now we can define the goal of libvirt: to provide a common and stable layer sufficient to securely manage domains on a node, possibly remote.

libvirt中,node即指物理机器,domain可以理解为虚拟机。
