Shouldn't happen if your host checks work properly and you have the
parents directive properly set up to match your environment.

Why are you reading netsaint docuementation? It's incredibly outdated in
general. In this particular regard however, the parents functionality
has remained the same.

Does the host check for xendom0 return a down status when it's down?
That should do what you want.

No, it would break your configuration since parent_map isn't a valid
nagios directive. I think if you verify that your host check for xendom0
does what you think it does you should be ok with the above
configuration.
