I'm going to apply this patch, but:

That you wrote this patch suggests that you're using the xend "managed
domains" feature.  This feature is not supported by the new xl/libxl
tools, and the current plans are to phase out xend.

Xend will still be in 4.1 but will very likely not be the default
toolstack in 4.1.  Personally at some point I hope it will be
removed; it's unreliable and unmaintainable.

So you may want to consider a migration path away from xend "managed
domains".  The xl toolstack supports the init.d-based machinery for
automatically saving and restoring domains on dom0 reboot; if you need
a more heavyweight approach then XCP may be more to your liking.

Ian.
