Trap & Emulate

configname: CONFIG_KVM_MIPS_TE

Virtualization mode
└─>Trap & Emulate
In linux kernel since version 4.2 (release Date: 2015-08-30)  
Use trap and emulate to virtualize 32-bit guests in user mode. This
does not require any special hardware Virtualization support beyond
standard MIPS32/64 r2 or later, but it does require the guest kernel
to be configured with CONFIG_KVM_GUEST=y so that it resides in the
user address segment.
