Redundant Physical Connection for Virtual Servers (Erl, Naserpour)

How can a virtual server be kept connected when its physical connection fails?

Problem

If the virtual switch uplink port used by a virtual server fails, the virtual server becomes isolated and unable to connect to the network or any of its hosted IT resources.

Solution

A redundant, physical backup network connection is established for virtual servers

Application

A second physical network card is added to the physical host and is configured as a hot standby uplink port for the virtual switch.
