If you install the cpint package on the monitoring Linux to invoke CP commands,
you can issue SIGNAL directly from that instance. It would need the correct
directory authorization for shutting down other servers.

Subject: Signaling VM from Linux


Hi.

Here's the background.

We're trying to setup a solution to shutdown all Linux Guests in case
the UPS starts working on Batteries.

For that, we want to have a Linux Guest monitoring the UPS state and
reporting to VM so it can issue a Shutdown signal to all the Linux
Guests. We've already figured out the part of VM sending the Shutdown
signal to the Linux Guests, but we can't solve the rest.

How Can it be done?
Is there a better way?


Thanks.

Samuel.
