Problem with qemu_domain.c is that it's constantly growing. But there are few options for improvement. For instance, validation functions were moved out and now live in qemu_validate.c. We can do the same for PostParse functions, though since PostParse may modify domain definition, some functions need to be exported from qemu_domain.c.
