VIOM (ServerView Virtual-IO Manager)
The name of both the I/O virtualization technology used to change the MAC addresses of NICs and the software that performs the

virtual switch
A function provided by server virtualization software to manage networks of VM guests as virtual LAN switches.
The relationships between the virtual NICs of VM guests and the NICs of the physical servers used to operate VM hosts can be managed
using operations similar to those of the wiring of normal LAN switches.
VLAN (Virtual LAN)
A splitting function, which enables the creation of virtual LANs (seen as differing logically by software) by grouping ports on a LAN
switch.
Using a Virtual LAN, network configuration can be performed freely without the need for modification of the physical network
