Service management - Start/stop guests

Table of Contents

Description

Manual start and stop of managed guests.

Examples

Example1 - Guest stop with no stop script defined

Context: Red Hat Enterprise Linux 7.1 server with CHARON-AXP V4.7 installed, as4100/pluto guest running

Due to the absence of stop script, the service receives a SIGKILL signal and then, once stopped, is considered as failed:

Example2 - Guest start

Context: Red Hat Enterprise Linux 7.1 server with CHARON-AXP V4.7 installed, as4100/pluto guest stopped/failed (see above)

We can optionally have a continuous view of the log file:

...

The error message above (black/red) is expected the first time the virtual machine is started. It tells the .bin file does not exist as it is initialized when console parameters are set

Press CTRL-C at any time to leave the log file view.

Example3 - Guest stop with stop script defined

Context: Red Hat Enterprise Linux 7.1 server with CHARON-AXP V4.7 installed, as4100/pluto guest running (not booted). Stop script created and customized, using the "expect" utility (see "Service management - Create/Edit guest stop script") and the expect script example provided in the kit.

We can see below the guest has been properly stopped and is now in INACTIVE / REQUESTED state:

As we are running Red Hat Enterprise Linux 7.1 server, systemd allows us to check the status of the service.

Use option 4 of the menu can help seeing the result of the shutdown commands:

We can see above, the expect utility has been used, did connect to the console, found the SRM prompt (the as4100 was not booted) and then issued a "power off" command ( This depends of what you decide to display in the guest stop script)

With Linux systems not using systemd (Red Hat Enterprise Linux 6), we would have to look into a log file defined in the stop script / output redirection. For more information, see "Service management - Create/Edit guest stop script".
