11 | other operating systems inside virtual machines (guests). | ||

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