        Description of the hypervisor mode

==================================

The hypervisor mode of dynamips allows you to run simultaneously

many virtual router instances, and to simulate ATM, Ethernet

or Frame-Relay networks. 

Available since version 0.2.5.

Running dynamips in hypervisor mode

===================================

dynamips -H [:]

Managing the hypervisor

=======================

You can connect directly to the TCP control port with telnet, or use

dynagen/dynagui that will pass commands transparently. The second method

is highly recommended.

The command syntax is simple:   [arguments...]

For example: "vm start R1" starts virtual instance named "R1".

The modules that are currently defined are given below:

  * hypervisor   : General hypervisor management
