# # KVM configuration # source "virt/kvm/Kconfig" menuconfig VIRTUALIZATION bool "Virtualization" depends on HAVE_KVM || X86 default y ---help--- 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.

You will need a fairly recent processor equipped with virtualization extensions. You will also need to select one or more of the processor modules below. This module provides access to the hardware capabilities through a character device node named /dev/kvm. To compile this as a module, choose M here: the module will be called kvm. If unsure, say N. config KVM_INTEL tristate "KVM for Intel processors support" depends on KVM # for perf_guest_get_msrs(): depends on CPU_SUP_INTEL ---help--- Provides support for KVM on Intel processors equipped with the VT extensions. To compile this as a module, choose M here: the module will be called kvm-intel. config KVM_AMD tristate "KVM for AMD processors support" depends on KVM ---help--- Provides support for KVM on AMD processors equipped with the AMD-V (SVM) extensions. To compile this as a module, choose M here: the module will be called kvm-amd. config KVM_MMU_AUDIT bool "Audit KVM MMU" depends on KVM && TRACEPOINTS ---help--- This option adds a R/W kVM module parameter 'mmu_audit', which allows auditing of KVM MMU events at runtime. config KVM_DEVICE_ASSIGNMENT bool "KVM legacy PCI device assignment support (DEPRECATED)" depends on KVM && PCI && IOMMU_API default n ---help--- Provide support for legacy PCI device assignment through KVM. The kernel now also supports a full featured userspace device driver framework through VFIO, which supersedes this support and provides better security. If unsure, say N. # OK, it's a little counter-intuitive to do this, but it puts it neatly under # the virtualization menu. source drivers/vhost/Kconfig source drivers/lguest/Kconfig endif # VIRTUALIZATION
