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
