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. |
|
|

If you say N, all options in this submenu will be skipped and disabled. |

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 |

user address segment. |

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