嵌套虚拟化

物理机: windows 10 专业版，
k8s node节点: virtualbox 6.1.22 虚拟机，使用嵌套虚拟化，ubuntu 18.04.5, k8s 1.18.20。

Dockerfile

进入 windows7下载目录（此目录应当只有一个iso)构建镜像

cd /media/sf_backup/dev/os/windows7

cat <<EOF | sudo tee Dockerfile
FROM scratch
ADD --chown=107:107 cn_windows_7_ultimate_with_sp1_x64_dvd_u_677408.iso /disk/
EOF

docker build -t w7:v1 .

w7-c.yaml

下面的配置，在安装时，鼠标有些飘，安装好后，恢复正常。
注意：安装好系统后，在设备管理中，把一些没有安装的驱动，安装好。
