+ Say Y here to get to see options for using your Linux host to run
+ other operating systems inside virtual machines (guests).
+ This option alone does not add any kernel code.

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

+ Use the MIPS Virtualization (VZ) ASE to virtualize guests. This
+ supports running unmodified guest kernels (with CONFIG_KVM_GUEST=n),
+ but requires hardware support.
