Something like 'test_status_information'. This is a generic test case for query-machines, and I don't expect it to be specific for validating support-status. > > > + self.vm.launch() > > + machines = self.vm.command('query-machines') > > Also I suggest to assert you got at least on machine, so ensure > 'query-machines' returning nothing doesn't pass unnoticed. Good idea. I will send this in v2 or as a follow up patch. Thanks!

Export machine type deprecation information through the query-machines QMP command. With this, libvirt and management software will be able to show this information to users and/or suggest changes to VM configuration to avoid deprecated machines.
