Eucalyptus provides the network infrastructure that enables access to and from VM instances. Typically, these VMs reside on virtual subnets that must be configured to be separate and distinct from the physical network on which Eucalyptus components interact. Eucalyptus creates these virtual subnets during instance creation and disposes of them when the last instance on a particular virtual subnet is terminated. Note that the administrator must ensure that the virtual subnet IP address space does not contain, is not contained by, and does not conflict with any part of the physical network IP address space.

Eucalyptu提供网络基本设施来访问VM实例。通常，这些实例依赖于虚拟子网。这些虚拟子网在配置时，必须区别于Eucalyptu组件交互的物理网络。Eucalyptu在实例被创建时，构建虚拟子网；在最后一个实例被终止时，分解这些子网。注意：管理员要确保这些虚拟子网IP地址空间不能包含，或者被包含，或者与物理网络IP地址空间冲突。
