that means libvirt successfully parsed the changed XML file.
The elements libvirt does not parse will not appear in the changed
configuration. Usually those should get caught by the schema validation,
but it's not perfect.

What were the exact changes you were trying to make?

Calling 'virsh define' with the same domain name and UUID in the XML and
'virsh edit' is equivalent - both call virDomainDefineXMLFlags under the
hood.
