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

Use the MIPS Virtualization (VZ) ASE to virtualize guests. This

supports running unmodified guest kernels (with CONFIG_KVM_GUEST=n),
