This patch introduces the <maxphysaddr mode='passthrough'/> <maxphysaddr mode='emulate' bits='42'/> sub element of /domain/cpu, which allows specifying the guest virtual CPU address size. This can be useful if the guest needs to have a large amount of memory. If mode='passthrough', the virtual CPU will have the same number of address bits as the host. If mode='emulate', the mandatory bits attribute specifies the number of address bits.
