A.2. Explanation of Settings in the New Network Interface and Edit Network Interface Windows
These settings apply when you are adding or editing a virtual machine network interface. If you have more than one network interface attached to a virtual machine, you can put the virtual machine on more than one logical network.

Field Name
|
Description
|
|---|---|
|
Name
|
The name of the network interface. This text field has a 21-character limit and must be a unique name with any combination of uppercase and lowercase letters, numbers, hyphens, and underscores.
|
|
Profile
|
Logical network that the network interface is placed on. By default, all network interfaces are put on the ovirtmgmt management network.
|
|
Type
|
The virtual interface the network interface presents to virtual machines. VirtIO is faster but requires VirtIO drivers. Red Hat Enterprise Linux 5 and higher includes VirtIO drivers. Windows does not include VirtIO drivers, but they can be installed from the guest tools ISO or virtual floppy disk. rtl8139 and e1000 device drivers are included in most operating systems.

|
Custom MAC address
|
Choose this option to set a custom MAC address. The Red Hat Virtualization Manager automatically generates a MAC address that is unique to the environment to identify the network interface. Having two devices with the same MAC address online in the same network causes networking conflicts.
|
|
Link State
|
Whether or not the network interface is connected to the logical network.
|
|
Card Status
|
Whether or not the network interface is defined on the virtual machine.
