KVM嵌套虚拟化配置

KVM嵌套虚拟化配置

(1)先查看我们的虚拟机A支不支持虚拟化，通过命令lscpu

Or :  

    #查看当前系统是否支持nested

    systool -m kvm_intel -v  | grep -i nested

   nested              ="N"

    #或者这样查看

   cat /sys/module/kvm_intel/parameters/nested

N

 

(2) 开机启动该nested

1># echo "options kvm-intel nested=1">> /etc/modprobe.d/kvm-intel.conf

重启主机

2> # rmmod kvm_intel

    #modprobe kvm-intel nested=1

    #cat /sys/module/kvm_intel/parameters/nested

    Y

不重启主机

 

(3) 建议VMX支持虚拟机
