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

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

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