This patch maps /domain/cpu/maxphysaddr into -cpu parameters: - <maxphysaddr mode='passthrough'/> becomes host-phys-bits=on - <maxphysaddr mode='emualte' bits='42'/> becomes phys-bits=42 Passthrough mode can only be used if the chosen CPU model is 'host-passthrough'. Also validate that an explicitly specified bits value does not exceed the physical address bits on the host. The feature is available since QEMU 2.7.0.
