  11           other operating systems inside virtual machines (guests).
  12           This option alone does not add any kernel code.

  39           Use trap and emulate to virtualize 32-bit guests in user mode. This
  40           does not require any special hardware Virtualization support beyond
  41           standard MIPS32/64 r2 or later, but it does require the guest kernel
  42           to be configured with CONFIG_KVM_GUEST=y so that it resides in the
  43           user address segment.

  49           supports running unmodified guest kernels (with CONFIG_KVM_GUEST=n),
  50           but requires hardware support.
