qapi: Report support for -device cpu hotplug in query-machines
For management apps it's very useful to know whether the selected machine type supports cpu hotplug via the new -device approach. Using the presence of 'query-hotpluggable-cpus' alone is not enough as a witness. Add a property to 'MachineInfo' called 'hotpluggable-cpus' that will report the presence of this feature. Example of output: { "hotpluggable-cpus": false, "name": "mac99", "cpu-max": 1 }, { "hotpluggable-cpus": true, "name": "pseries-2.7", "is-default": true, "cpu-max": 255, "alias": "pseries" }, Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
