I have just configured a VM to be aware of our UPS state via a serial port to ethernt adapter.
If power fails - when on batteries - the UPS signals the VM which can then run a batch file to shutdown the rest of the VM's and finally shut itself down.
This leaves my host powered on - I do not want this to just drop when the power finaly fails.
I use a serial connection from the APC 3000 UPS (as I mentioned i have to interface this with a 'Star5tech' serial to ethernet adapter in order for the VM's to comminicate)
How can I signal or command the Host server to shutdown at the end of the sequence?
Can I issue a delayed shutdown command from the last VM before this shuts down ?
