There is already a check for domains with the same name in
XendDomainInfo.check_name. We should fix that check instead of adding
another check. Could you try the attached patch which removes the
check if a domain "is terminated" and thus allows creation of a domain
with the same name?
It's arguable if this should be allowed or not, but if we allow it,
then we need to find the root cause of the error you're seeing...
