CHARON-VAX symbolic links

Each model of CHARON-VAX has a symbolic link defined to point to the corresponding CHARON executable (see the table below). If the PATH is correctly defined, you can start a virtual machine by specifying the link followed by the configuration file. This is described further.

...

Running CHARON-VAX emulators

It is possible to run one or several instances of CHARON-VAX at the same time if your license allows it.

...

Running from the console

Copy the selected configuration template from the "/opt/charon/cfg/" directory to some local file and set the correct privileges for the file to be edited.

...

Running as system service (daemon)

It is possible to run CHARON-VAX as a daemon (service). In this case the CHARON-VAX process will be detached from its parent process and from the terminal window in which it runs.

Follow the description below to install and execute CHARON-VAX as a daemon:

Installation and start of CHARON-VAX service

1. Copy the sample script "/opt/charon/bin/charon.service" ( "/opt/charon/bin/charon" for Red Hat  Linux 6.x) to the "/usr/lib/systemd/system/" directory (or to your home directory for Red Hat Enterprise Linux 6.x).

   Example:

   Red Hat Linux 6.x	$ cp /opt/charon/bin/charon /my_services/mv3k6_service $ chmod 755 /my_services/mv3k6_service
   Red Hat Linux 7.x and CentOS 7.x	$ cp /opt/charon/bin/charon.service /usr/lib/systemd/system/mv3k6.service $ chmod 755 /usr/lib/systemd/system/mv3k6.service

   
   

2. Edit the renamed file to replace sample values of the following parameters.

   Example:

   Red Hat Linux 6.x	exec="/opt/charon/bin/mv3k6" prog="my_mv3k6" config="/my_services/mv3k6-service.cfg"
   Red Hat Linux 7.x and CentOS 7.x	ExecStart=/opt/charon/bin/mv3k6 -d /my_services/mv3k6-service.cfg WorkingDirectory=/my_services

    "my_mv3k6" is a service name in the example above

            

3. Create and edit the configuration file ("/my_services/mv3k6-service.cfg" in the examples above) the way it was described before and make sure the following pre-requisites are met:

   • OPA0 must be configured as a virtual port or physical console, not as an operator console.

     Example:

     load virtual_serial_line OPA0 port=10003 #load operator_console OPA0

     
     

   • Use only absolute paths to log, toy clock, nvram files and all the other data such as disk images, etc. The names of the references files must be unique.

     Example:

     ... set session log="/my_services/my_mv3k6.log" set toy container="/my_services/my_mv3k6.dat" load RQDX3/RQDX3 DUA set DUA container[0]="/my_services/mv3k6_daemon_boot_disk.vdisk" ...

     
     

   • Make sure the same physical devices are not used by other CHARON-VAX daemons and the OPA0 console port number is unique across the CHARON server.
     
     

Once configuration file is ready, execute the following commands (based on the examples above) to install and start CHARON-VAX as a daemon:

...

Stopping CHARON-VAX service

To stop a CHARON-VAX daemon, use the following commands.

Example:

Please note that before stopping a CHARON-VAX service, a clean shutdown of the operating system running on the virtual machine has to be performed.

Removing CHARON-VAX service

To remove a CHARON-VAX daemon use the following commands.

Example:
