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.
Support running unmodified book3s_32 guest kernels in virtual machines on book3s_32 host processors. This module provides access to the hardware capabilities through a character device node named /dev/kvm. If unsure, say N.
Support running unmodified book3s_64 and book3s_32 guest kernels in virtual machines on book3s_64 host processors. This module provides access to the hardware capabilities through a character device node named /dev/kvm. If unsure, say N.
Support running unmodified 440 guest kernels in virtual machines on 440 host processors. This module provides access to the hardware capabilities through a character device node named /dev/kvm. If unsure, say N.
Calculate elapsed time for every exit/enter cycle. A per-vcpu report is available in debugfs kvm/vm#_vcpu#_timing. The overhead is relatively small, however it is not recommended for production environments. If unsure, say N.
Support running unmodified E500 guest kernels in virtual machines on E500 host processors. This module provides access to the hardware capabilities through a character device node named /dev/kvm. If unsure, say N.
