因为目前正在做autopkgtest的测试，所以这里得简短介绍下lxc的一些基本用法。
启动lxc
root@unmatched:~# lxc-start -n autopkgtest-unstable-riscv64
root@unmatched:~# lxc-ls -f
NAME STATE AUTOSTART GROUPS IPV4 IPV6 UNPRIVILEGED
autopkgtest-unstable-riscv64 RUNNING 0 - 10.0.3.17 - false
查看bridge
root@unmatched:~# grep net /var/lib/lxc/autopkgtest-unstable-riscv64/config
lxc.net.0.type = veth
lxc.net.0.link = lxcbr0 # 在host上的bridge is lxcbr0
root@unmatched:~# ifconfig lxcbr0
lxcbr0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

cd container
lxc-attach -n autopkgtest-unstable-riscv64
检查是否安装
root@autopkgtest-unstable-riscv64:~# dpkg --status ifupdown
Package: ifupdown
Status: install ok installed
