So what I hear you say is: Hook the UPS to the physical machine Have the host OS monitor the UPS's state When the UPS signals the host it sends a SIGHUP to the Virtual Machines The VMs should then interpret the SIGHUP as a Shutdown command Is that what you had in mnd? Does anyone know if that's how it works? Chuck
Yes.The signal may depend on the VM design though. I would hope they have used enough sense to honor some standard.
This really is a near trivial problem. The guests shutdown cleanly during a normal shutdown, yes? Why should a shutdown instituted by UPS software or even admin written (monitoring) scripts be any different?
