pve 下 lxc 容器安装 k3s 的问题

有个小主机安装了 pve 并且创建了一个 ubuntu 的 lxc 容器 在这个容器里安装 k3s 但是 pod 一直没有创建成功 kubectl describe 查看原因是

mount: /var/lib/kubelet/pods/6357e3c9-f6f5-499f-ab87-c51e7a6699cf/volumes/kubernetes.io~projected/kube-api-access-dc9xv: must be superuser to use mount. dmesg(1) may have more information after failed mount system call. 

导致 但是我使用 root 账户执行也出现这个错误 strace 查看是
