Same here.  I've got production systems from the extreme management backend
to the customer-facing side of things running on xen machines, and they've
been totally stable.  Heartbeat adds an extra level of security for the
really mission-critical stuff.

Managing the nagios text config files has always been less of pain than
managing a config tool, for me.  70+ hosts can be boiled down to 10 or so
host groups, and then services.cfg isn't too complicated at all.
