Y
root@pve:~#
1.PVE主机嵌套虚拟化未开启，则先必须先关闭所有的虚拟机，
2.强制关闭命令：qm stop 100（虚拟机ID）
3.执行以下命令开启嵌套虚拟化
# 开启嵌套虚拟化
modprobe -r kvm_intel
modprobe kvm_intel nested=1
cat /sys/module/kvm_intel/parameters/nested
echo "options kvm_intel nested=1" >> /etc/modprobe.d/modprobe.conf # 将开启嵌套虚拟化设置开机自启
选择默认的KVM类型
进入etc/pve/nodes/pve/qemu-server/目录下，修改PVE虚拟机的配置文件，添加以下内容。
root@pve:/etc/pve/nodes/pve/qemu-server# grep args 109.conf
args: -cpu 'kvm64,enforce,+kvm_pv_eoi,+vmx,+kvm_pv_unhalt,+lahf_lm,+sep'
选择虚拟机CPU类型为host
