Are you disagreeing with the message (which your patch doesn't fix)
or with the semantic of the check (and then why allow to create a domain
reusing the UUID of another defined but not running domain, I can only
see confusion or security problems in doing so)
The act of creating a domain reusing the UUID of another defined but not
running domain is presumably an action taken with intent to rename that
other domain (and thus should undefine the prior domain holding that
UUID in the process... which, admittedly, the given patch didn't
explicitly do).
Anyhow, two patches attached; one revises the error messages, while the
other improves behavior with the semantics I assumed, to explicitly
undefine any duplicates found during a create; I'm happy with either.
