If you just want to restart the domain on another host, thn drdb should
do the job OK, though you could just as easily write a simple script to
monitor the liveness of the application, and if required, issue an "xm
-h hosta destroy mydom; xm -h hostb create mydom" etc.

In future Xen versions we intend to add support for light-weight
checkpoints and s/w-implemented fault tolerance.
