我这里当然不是跟你说装PVE然后装LXC,这样不但不环保,而且…

我这里用的是原生的LXC,不需要替换内核,Ubuntu用户可以直接通过apt install lxd lxd-client安装,其他用户可以通过安装snap然后安装lxd,具体看snap商店.

然后初始化一下安装(一切默认也没问题):

root@debian:~# lxd init
WARNING: cgroup v2 is not fully supported yet, proceeding with partial confinement
Would you like to use LXD clustering? (yes/no) [default=no]: 
Do you want to configure a new storage pool? (yes/no) [default=yes]:

root@debian:~# 

然后创起一个Ubuntu.

初次进入容器需要一些方法.

lxc exec ubuntu -- /bin/bash

就可以愉快玩耍了,至于IP怎么转发分配,和普通VM也没什么区别.

当然,LXC是共享宿主内核的,项目的更多内容请看:https://linuxcontainers.org/lxd/getting-started-cli/
