If it is not possible to save/restore a backend domain it is ok. The
reason why stumbled across this problem was that the xendomains script
tried to save the domains on reboot of Domain-0. That failed of course.
Then xendomains tries to shutdown these remaining domains. That fails
too and the host did not reboot for a long time. IMHO that is the main
problem.
The xen scripts that lie around in the system should be aware of the
fact that certain domains cannot be saved, and handle this situation
gracefully.

You are right. After destroying xendom1 the zombie domain went away too.
