I am far from an expert on this topic, but under what situation is it =
good to take any OS down suddenly?  Is this an unavoidable event of some =
sort?

If this is a timed event, that happens on a regular basis, then you =
should be able to issue a timed shutdown prior to that so that the =
operating system goes down cleanly.

Any file system that is taken down abruptly, repeatedly will see =
degradation.  Databases and open files, not to mention any data that is =
being written from/to the hard disk are all meant to be taken down and =
cleared out properly.

I'm not certain that a different file system is the solution, it might =
just be a band-aid on the greater problem, which is eliminating the =
sudden power loss that's simulated by shutting off a VM.
