DAHDi卡无法虚拟化的曲线解决方案：LXC容器化
将Openvox D210语音卡装入ESXi主机直通给freepbx虚拟机后会不定时掉线，排查下来应该是虚拟机中断的问题，找遍全网也没有解决方案，只好曲线救国，将语音卡通过设备映射的方式映射给LXC容器内的freepbx。

安装lxc
apt install lxc libpam-cgfs
lxc-checkconfig
常用命令
lxc-create -n name -f config_file
lxc-version 用于显示系统LXC的版本号（可以通过此命令判断系统是否安装了lxc）
lxc-checkconfig 用于判断linux内核是否支持LXC
lxc-create用于创建一个容器
lxc-execute 用于在一个容器执行应用程序
lxc-start 用于在容器中执行给定命令
lxc-kill 发送信号给容器中的第一个用户进程（容器内部进程号为2的进程）
lxc-stop 用于停止容器中所有的进程
lxc-destroy 用于销毁容器
lxc-cgroup 用于获取或调整与cgroup相关的参数
lxc-info 用户获取一个容器的状态
lxc-monitor 监控一个容器状态的变换，当一个容器的状态变化时，此命令会在屏幕上打印出容器的状态
lxc-ls -f 列出当前系统所有的容器
lxc-start
lxc-attach -n
lxc-console
lxc-copy -n ubuntu1 -N clone_ubuntu1 复制容器
lxc-snapshot -n ubuntu1 创建快照
软关机：
lxc-stop -n
重启容器：
lxc-stop -n
例如我们要重启rstudio这个容器的话：
lxc-stop -n
如果无法正常重启，可以尝试硬关闭：
lxc-stop -n
如果要先尝试软关机再若180秒后依旧无反应的话再硬关闭则：
lxc-stop -n rstudio -k -t 180
ls /var/lib/lxc 容器目录
ls /usr/share/lxc/templates/ 查看当前模板

从镜像站创建lxc容器 这里需要创建debian11的容器因为dahdi的驱动还不支持debian12

按照教程在LXC容器中运行的debian11内安装freepbx，主机上安装驱动的操作也要做
debian11中安装FreePBX16
进入freepbx 手动安装dahdi扩展模块
LXC内遇到的问题解决方案:
如有如下报错需要，将当前内核版本文件夹内复制到/lib/modules/6.1.0-17-amd64
systemctl status dahdi
Jan 10 08:36:02 dahdi[233]: modprobe: FATAL: Module dahdi not found in directory /lib/modules/6.1.0-17-amd64
freepbx内dadhi页面显示报错DAHDi Doesn't appear to be running. Click the 'Restart DAHDi & Asterisk' button below
asterisk -rvvvv
重新载入dahdi模块
module unload chan_dahdi.so
module load chan_dahdi.so
拷贝文件到LXC内
/usr/lib/asterisk/modules/chan_dahdi.so
/usr/lib/libpri.so.1.4
/usr/lib/x86_64-linux-gnu/libss7.so.2.0
