HYPERVISOR_MODE(7)

NAME
hypervisor mode - allows you to run simultaneously many virtual router instances, and to simulate ATM, Ethernet or Frame-Relay networks.

SYNOPSIS
dynamips -H tcp_port

DESCRIPTION
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: <module> <function> [arguments...] For example: "c7200 start R1" starts virtual instance named "R1".

The modules that are currently defined are given below:
    hypervisor General hypervisor management

    vm  General virtual machine (VM) management

    c7200
        Virtual instances of Cisco 7200

    c3600
        Virtual instances of Cisco 3600

    nio Network Input/Output (NIO) descriptors

    nio_bridge
        NIO bridges (shared media)

    atmsw
        ATM switches

    frsw
        Frame-Relay switches

    ethsw
        Ethernet switches

Hypervisor management module

    hypervisor module_list
        Display the module list.

    hypervisor cmd_list <module>
        Display commands recognized by the specified module.

    hypervisor close
        Close the current session.

    hypervisorstop
        Destroy all objects and stop hypervisor.

    hypervisor reset
        Destroy all objects (used to get an empty configuration)

    hypervisor working_dir <directory>
        Set the directory to use to store files.

    hypervisor save_config <filename>
        Save the configuration of all objects into the specified file.

Virtual Machine module ("vm")

    vm list
        List all VM instances (c7200, c3600).

    vm set_debug_level <instance_name> <level>
        Set the debug level (which is a number) for a VM. By default, no specific debug is enabled (level = 0).

    vm set_ios <instance_name> <ios_file>
        Set the IOS image file to use. There is no default.

    vm set_config <instance_name> <config_reg>
        Set the config register value.

    vm set_ram <instance_name> <ram_size>
        Set the RAM size, specified in Mbytes.

    vm set_nvram <instance_name> <nvram_size>
        Set the NVRAM size, specified in Kbytes.

    vm set_ram_mmap <instance_name> <0|1>
        Enable/Disable use of a mapped file to simulate router memory. By default, a mapped file is used. This is a bit slower, but requires less memory.

    vm suspend <instance_name>
        Suspend execution of the instance.

    vm resume <instance_name>
        Resume execution of the instance.

    vm set_clock_divisor <instance_name> <clock_div>

    vm set_idle_pc <instance_name> <pc_value>
        Set the idle Pointer Counter (PC). You must determine it through the method explained in the main README file.

    vm set_exec_area <instance_name> <area_size>
        Set the exec area size. The exec area is a pool of host memory used to store pages translated by the JIT (they contain the native code corresponding to MIPS code pages).

    vm set_con_tcp_port <instance_name> <tcp_port>
        Set the TCP port to use for console. By default, no TCP port is chosen, meaning that you cannot get access to the console.

        Set the TCP port to use for AUX port. By default, no TCP port is chosen, meaning that you cannot get access to the AUX port.

    vm cpu_info <instance_name> <cpu_id>
        Show info about the CPU identified by "cpu_id". The boot CPU (which is typically the only CPU) has ID 0.
