This VMware®
Using a Proxy with vSphere
Virtual Serial Ports
manual provides information about developing a virtual
serial port concentrator for use in the vSphere environment. This guide describes
capabilities of a proxy implementation that supports the VMware telnet extension, and
provides information about configuring a virtual serial port for a proxy connection.The use case for a virtual serial port proxy
is to maintain specific network connections during vMotion, which is the movement of
virtual machines from one ESXi host to another. Note that this method uses telnet so is
best deployed in a private data center.
