The problem is that the XenAPI driver currently has a bug here. It should check (via UUID and name) if the domain XML refers to an existing domain and update this domain or the if the given domain XML doesn't refer to an existing domain and define a new one instead. The XenAPI driver does not check this and always defines a new domain. So unfortunately you cannot edit the config of an existing domain until this bug is fixed,

You might be able to workaround this bug by undefining the domain first and then redefining it.
