KVM在linux3.6.6中支持

　　KVM模块编译的Makefile文件在/arch/x86/kvm/Makefile  内容如下
　　ccflags-y += -Ivirt/kvm -Iarch/x86/kvm
　　CFLAGS_x86.o := -I.
CFLAGS_svm.o := -I.
CFLAGS_vmx.o := -I.
　　kvm-y   += $(addprefix ../../../virt/kvm/, kvm_main.o ioapic.o \
    coalesced_mmio.o irq_comm.o eventfd.o \
    assigned-dev.o)
kvm-$(CONFIG_IOMMU_API) += $(addprefix ../../../virt/kvm/, iommu.o)
kvm-$(CONFIG_KVM_ASYNC_PF) += $(addprefix ../../../virt/kvm/, async_pf.o)
　　kvm-y   += x86.o mmu.o emulate.o i8259.o irq.o lapic.o \
      i8254.o timer.o cpuid.o pmu.o
kvm-intel-y  += vmx.o
kvm-amd-y  += svm.o
　　obj-$(CONFIG_KVM) += kvm.o
obj-$(CONFIG_KVM_INTEL) += kvm-intel.o
obj-$(CONFIG_KVM_AMD) += kvm-amd.o

　　
　　配置选项在/arch/x86/kvm/Kconfig 内容如下
　　#
# 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.
　　If you say N, all options in this submenu will be skipped and disabled.
　　if VIRTUALIZATION
　　config KVM
tristate "Kernel-based Virtual Machine (KVM) support"
depends on HAVE_KVM
# for device assignment:
depends on PCI
# for TASKSTATS/TASK_DELAY_ACCT:
depends on NET
select PREEMPT_NOTIFIERS
select MMU_NOTIFIER
select ANON_INODES
select HAVE_KVM_IRQCHIP
select HAVE_KVM_EVENTFD
select KVM_APIC_ARCHITECTURE
select KVM_ASYNC_PF
select USER_RETURN_NOTIFIER
select KVM_MMIO
select TASKSTATS
select TASK_DELAY_ACCT
select PERF_EVENTS
select HAVE_KVM_MSI
---help---
   Support hosting fully virtualized guest machines using hardware
   virtualization extensions.  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
  audit  KVM MMU at runtime.
　　# 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
