Network virtualization is the most complex part of virtualization technology and the most difficult to learn. But because the network is a very important resource in virtualization, the hard bones must be chewed down.To give you a visual understanding of the complexity of your virtualization network, seeThis is the logical diagram of a virtual network of compute nodes (which can be understood as KVM hosts) on the OpenStack official web site, with many
