/bin/sh: 1: rpm: not found若计算节点不是裸金属服务器，则还需要打这个 label ，即可自动安装 PVM kubectl label nodes cube.tencent.com/allow-pvm-bootstrap=true --overwrite
and if I don't use this tag( my node supports nested virtualization I don't want to install custom kernel) it will failed because k8s can't find node to schedule.
