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.

To exit from the CHARON-VAX emulator use the following methods:

Configuration How to exit

No change to the template configuration file (not recommended) Kill the console from where CHARON runs (CTRL-C for example) or kill the CHARON process

Enable "F6" button in configuration file to trigger exit from CHARON:

#----------------------------------------------------------------------------

# Uncomment to allow 'F6' to terminate the running emulator.

#----------------------------------------------------------------------------

set OPA0 stop_on = F6

Press the "F6" key

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

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 8x, 7.x and CentOS 8x, 7.
x
$ cp /opt/charon/bin/charon.service /usr/lib/systemd/system/mv3k6.service
$ chmod 755 /usr/lib/systemd/system/mv3k6.service

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 8.x, 7.x and CentOS 8.x, 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

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:

Red Hat Linux 6.x	`# ln -sf /my_services/mv3k6_service /etc/init.d/mv3k6_service` `# chkconfig mv3k6_service on` `# service mv3k6_service start`
Red Hat Linux 8.x, 7.x and CentOS 8.x, 7.x	`# systemctl enable mv3k6.service` `# systemctl start mv3k6.service`

Info

title	Red Hat Linux 7.x and CentOS 7.x

If you update the /usr/lib/systemd/system/<my virtual machine>.service file, the following command must be executed in order to take changes into account:

# systemctl daemon-reload

...

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

Example:

Red Hat Linux 6.x	`# service mv3k6_service stop`
Red Hat Linux 8.x, 7.x and CentOS 8.x, 7.x	`# systemctl stop mv3k6`

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.

...

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

Example:

Red Hat Linux 6.x	`# chkconfig mv3k6_service off` `# chkconfig --del mv3k6_service` `# rm -f /etc/init.d/mv3k6_service`
Red Hat Linux 8.x, 7.x and CentOS 8.x, 7.x	`# systemctl disable mv3k6.service # rm -f /usr/lib/systemd/system/mv3k6.service`

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