kvm虚拟化技术实战记录（1）——配置kvm

1.创建目录/root/my_kvm/code

2.cd /root/my_kvm/code

3.git clone git://git.kernel.org/pub/scm/virt/kvm/kvm.git kvm.git

4.cd kvm.git

5.make meanuconfig



6.选择 Virtualization后进入详细配置，如下图：



7.编辑完后保存退出，会在kvm.git下面生成一个.config文件

8.确认下文件中几个重要的参数如下：

CONFIG_HAVE_KVM=y

CONFIG_HAVE_KVM_IRQCHIP=y

CONFIG_HAVE_KVM_IRQFD=y

CONFIG_HAVE_KVM_IRQ_ROUTING=y

CONFIG_HAVE_KVM_EVENTFD=y

CONFIG_KVM_APIC_ARCHITECTURE=y

CONFIG_KVM_MMIO=y

CONFIG_KVM_ASYNC_PF=y

CONFIG_HAVE_KVM_MSI=y

CONFIG_HAVE_KVM_CPU_RELAX_INTERCEPT=y

CONFIG_KVM_VFIO=y

CONFIG_KVM_GENERIC_DIRTYLOG_READ_PROTECT=y

CONFIG_KVM_COMPAT=y

CONFIG_VIRTUALIZATION=y

CONFIG_KVM=m

CONFIG_KVM_INTEL=m

# CONFIG_KVM_AMD is not set

CONFIG_KVM_MMU_AUDIT=y
