From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com&gt; If a VM is just in one network, it may not access other machines in different networks. In most product environment, more networks are needed. Such as a network management, a service manages all the VMs in one network. Such management system is isolated from the internet for security reasons. And a more public network is needed for a VM to access the internet. So a vm with more networks is a common scenario.
