Currently -d guest_errors enables logging of different invalid actions by the guest such as misusing hardware, accessing missing features or invalid memory areas. The memory access logging can be quite verbose which obscures the other messages enabled by this debug switch so separate it by adding a new -d invalid_mem option to make it possible to control it independently of other guest error logs.
