 -        Select this option if you want to run the kernel as a guest under
 -        the KVM hypervisor. This will add detection for KVM as well  as a
 -        virtio transport. If KVM is detected, the virtio console will be
 -        the default console.

 -      help
 -        This kernel feature is useful for number crunching applications
 -        that may need to compute untrusted bytecode during their
 -        execution. By using pipes or other transports made available to
 -        the process as file descriptors supporting the read/write
 -        syscalls, it's possible to isolate those applications in
 -        their own address space using seccomp. Once seccomp is
 -        enabled via /proc/<pid>/seccomp, it cannot be disabled
 -        and the task is only allowed to execute a few safe syscalls
 -        defined by each seccomp mode.
 -
 -        If unsure, say Y.
