Question

我试图在另一台机器上运行交叉编译的lxc映像，如下所示：我通过命令在ubuntu 14.04上创建了一个lxc image ：

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

我检查了创建的图像 customBusyBox 在此计算机上正常运行。现在我创建了 .tar.gz 文件，即 customBusyBox.tar.gz ，并将其复制到具有相同版本的ubuntu的另一台机器上，即14.04 via scp 命令。然后我将customBusyBox图像提取到 / var / lib / lxc 文件夹。然后作为超级用户，我尝试通过以下命令运行图像：

lxc-start -F -n customBusyBox

然后我收到了这个错误：

lxc-start: utils.c: safe_mount: 1746 No such file or directory - Failed to mount /lib64 onto /usr/lib/i386-linux-gnu/lxc/lib64
                                                                                                                              lxc-start: conf.c: mount_entry: 1650 No such file or directory - failed to mount '/lib64' on '/usr/lib/i386-linux-gnu/lxc/lib64'

我尝试在网上搜索其解决方案，但没有帮助：有人请建议一些解决方案。

我能够解决这个错误。

以下是第一台主机上创建的 customBusyBox 容器的配置文件：

# Template used to create this container: /usr/share/lxc/templates/lxc-busybox
# Parameters passed to the template:
# For additional config options, please look at lxc.container.conf(5)
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = lxcbr0
lxc.network.hwaddr = 00:16:3e:1d:e5:8c
lxc.rootfs = /var/lib/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 = /lib64 lib64 none ro,bind 0 0
lxc.mount.entry = /usr/lib64 usr/lib64 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

我从其他主机上的配置文件中删除了以下行：

lxc.mount.entry = /lib64 lib64 none ro,bind 0 0
lxc.mount.entry = /usr/lib64 usr/lib64 none ro,bind 0 0

然后我尝试了它也在那里成功运行。实际上在第二台主机上有不任何这样的目录，即 / lib64或/ usr / lib64 目前，这就是为什么这些目录会发生挂载错误。

配置文件出现在路径：/var/lib/lxc/<container-name>/

lxc-start：utils.c：safe_mount：1746没有这样的文件或目录 - 无法将/ lib64挂载到/ usr / lib / i386-linux-gnu / lxc / lib64
