Overview Virtualization allows for the creation of multiple virtual machines (VMs) that can run simultaneously on a single physical server. These VMs can communicate among each other and with other physical systems through virtual switches. Virtual switches are software entities that provide the functionality of a physical Ethernet switch. Coupled with virtual LAN (VLAN) technology, virtualization can be effectively used to set up complex network infrastructures for test, development, and production environments. For example, VLANs can provide traffic isolation channels and enhanced network security models for physical server hosts and the VMs running on them. VMware ESX Server software includes the VMotion feature, which allows for live migration of a VM from one physical server to another.
