Indeed. But before fixing this I wonder what the exact semantics of
domainCreateLinux are. Is it correct that we don't call
virDomainSaveConfiguration? 
If so we probably don't even need to check if the domain is running. The
mere existance of a domain with the same name/uuid should probably throw
an error already since having another domain by the same name/uuid known
to libvirt already can be a source of confusion for the user.
