最近优化一下家里的all in one，为了节约内存，决定用轻量化的lxc容器来替代虚拟机安装omv，步骤如下：

建立容器

用pve模版列表里自带的debian10镜像，下载一下，然后新建虚拟机，因为要直通硬盘，所以要特权主机，因为我还要在里面放docker，在选项中勾选嵌套。网络需要科学上网。

修改配置

修改pve主机的/etc/pve/lxc/{ID}.conf({ID}是你的LXC序号)，添加：

lxc.mount.auto: cgroup:rw
lxc.mount.auto: proc:rw
lxc.mount.auto: sys:rw

当然，如果你需要挂载设备，那需要加点别的，请看我的另一片文章。

容器内

输入一下命令：

#更新并重启，很重要，有时候不一开始就这样装不成功
apt update && apt upgrade -y && reboot
#添加仓库、密钥，安装依赖
apt-get install --yes gnupg
wget -O "/etc/apt/trusted.gpg.d/openmediavault-archive-keyring.asc" https://packages.openmediavault.org/public/archive.key
apt-key add "/etc/apt/trusted.gpg.d/openmediavault-archive-keyring.asc"

cat <<EOF >> /etc/apt/sources.list.d/openmediavault.list

然后就可以啦！直通硬盘请看我的另一篇LXC的文章。
