Berrangé When user doesn't request any explicit CPU model with libvirt or QEMU, a machine type specific CPU model is picked. Currently there is no way to determine what this QEMU built-in default is, so libvirt cannot report this back to the user in the XML config. This extends the "query-machines" QMP command so that it reports the default CPU model typename for each machine. Reviewed-by: Eric Blake Signed-off-by: Daniel P.
