Question

我对lxc了解不多，最近几天才开始研究它。

我尝试通过命令在linux 14.04LTS上创建一个Linux容器：

lxc-create -t /usr/share/lxc/templates/lxc-busybox -n OpenWrt

它通过lxc-start命令在那里运行良好。

然后 tar 将 OpenWrt.tar.gz 并复制在运行LEDE的Compex 主板上OS（ ARM体系结构）到目录 / srv / lxc / ，其中我解压它来获取 / srv / lxc / OpenWrt 目录。然后，当我尝试通过命令运行容器时： lxc-start -F -n OpenWrt，我收到以下错误：

  lxc-start 20160210174618.933 ERROR    lxc_conf - conf.c:instantiate_veth:2618 - failed to create veth pair (vethAPIAY5 and vethWJLSXO): Operation not supported
      lxc-start 20160210174618.936 ERROR    lxc_conf - conf.c:lxc_create_network:2962 - failed to create netdev
      lxc-start 20160210174618.936 ERROR    lxc_start - start.c:lxc_spawn:1088 - Failed to create the network.
      lxc-start 20160210174618.936 ERROR    lxc_start - start.c:__lxc_start:1346 - Failed to spawn container "OpenWrt".
      lxc-start 20160210174618.971 ERROR    lxc_start_ui - tools/lxc_start.c:main:366 - The container failed to start.
      lxc-start 20160210174618.971 ERROR    lxc_start_ui - tools/lxc_start.c:main:370 - Additional information can be obtained by setting the --logfile and --logpriority options.

然后我只是在/ srv / lxc / OpenWrt / config文件中保存的配置文件中注释了网络配置（前4行），如下所示：

#lxc.network.type = veth
#lxc.network.flags = up
#lxc.network.link = lxcbr0
#lxc.network.hwaddr = 00:16:3e:1d:e5:8c
lxc.rootfs = /srv/lxc/OpenWrt/rootfs
lxc.haltsignal = SIGUSR1
lxc.utsname = OpenWrt
lxc.tty = 1
lxc.pts = 1
lxc.cap.drop = sys_module mac_admin mac_override sys_time

# When using LXC with apparmor, uncomment the next line to run unconfined:
#lxc.aa_profile = unconfined
lxc.mount.entry = /lib lib none ro,bind 0 0
lxc.mount.entry = /usr/lib usr/lib none ro,bind 0 0
#lxc.mount.entry = /sys/kernel/security sys/kernel/security none ro,bind,optional 0 0
lxc.mount.auto = proc:mixed sys

并通过命令再次运行容器：

lxc-start -n OpenWrt -l trace -o logfile.log

这次出现格式错误，如下面的日志所示：

lxc-start 20160210181025.855 ERROR    lxc_start - start.c:start:1431 - Exec format error - Failed to exec "/sbin/init".

我的理解是我试图在ARM板上运行x86二进制文件，这就是我遇到此错误的原因。现在我 尝试在linux 14.04计算机上创建一个ARM兼容容器，以便它可以在运行LEDE OS的ARM Compex板上运行。我正在寻找在lxc-create命令中指定所需架构的选项，比如创建ARM ubuntu lxc conatiner，我找到了一个命令即：

lxc-create -n armubuntu -t ubuntu -- -a armhf -r precise

但是当我尝试通过以下命令创建一个busybox容器时：

lxc-create -n myOpenWrt -t busybox -- -a armhf

我收到了无效选项错误：

getopt: invalid option -- 'a'
lxc-busybox -h|--help -p|--path=<path> -s|--ssh={dropbear,openssh}

现在我在网上搜索任何类似的命令来为ARM体系结构或任何小尺寸的容器创建所需的busybox容器（实际上创建的ubuntu ARM容器大小为426 MB，无法在板上复制/测试）。

有人请建议。
