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

Running as system service (daemon)

...

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 Enterprise Linux/CentOS 7 & 8	$ 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 Enterprise Linux/CentOS 7 & 8	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:
