In this case most likely they don't have the subsection (it's only there=20 if you use "-cpu foo,hv_something"). A more likely source of breakage if you do savevm on master is that the=20 machine type changed between the time of the savevm and the time of the=20 release. We obviously do not guarantee that between releases. Paolo
