如何让ipv4 / inet在intel主机上运行的arm lxc容器中运行？
如果尝试在我的intel 64bit系统上创建armhf和arm64 / aarch64 lxc容器。
我在启动容器之前复制了相关的qemu文件。 /usr/bin/qemu-arm-static for arm和/usr/bin/qemu-aarch64-static for arm64。
当我创建其他基于intel的ubuntu容器时，我的eth0有一个ipv4地址。 （使用桥接网络）
我像这样创建arm64容器：
lxc launch ubuntu:15.04/arm64 arm64 cp /usr/bin/qemu-aarch64-static /usr/lib/lxd/containers/arm64/rootfs/usr/bin lxc start arm64
我没有做任何其他修改。
在arm64容器中，ifconfig显示：
eth0 Link encap:Ethernet HWaddr 00:16:3e:e4:d2:de inet6 addr: fe80::216:3eff:fee4:d2de/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:19 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2564 (2.5 KB) TX bytes:578 (578.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
尝试显而易见的事情：
/etc/init.d/networking start
yeilds
[....] Starting networking (via systemctl): networking.serviceFailed to get D-Bus connection: No such file or directory failed!
ifup eth0收益率
/sbin/ifup: failed to open lockfile /run/network/.ifstate.lock: No such file or directory
ip addr yeilds
Cannot open netlink socket: Address family not supported by protocol
运行各种不同的网络工具时Address family not supported by protocol似乎是一个常见的错误消息 – 可能是因为没有识别出没有ipv4地址。
类似dhcp客户端
root@ubuntu:/var/log# dhclient -v Internet Systems Consortium DHCP Client 4.3.1 Copyright 2004-2014 Internet Systems Consortium. All rights reserved. For info, please visit https://www.isc.org/software/dhcp/ Error getting interfaces; Address family not supported by protocol Can't get list of interfaces.
/etc/network/interfaces是
# The loopback network interface auto lo iface lo inet loopback # Source interfaces # Please check /etc/network/interfaces.d before changing this file # as interfaces may have been defined in /etc/network/interfaces.d # NOTE: the primary ethernet device is defined in # /etc/network/interfaces.d/eth0 # See LP: #1262951 source /etc/network/interfaces.d/*.cfg
和eth0.cfg是
# The primary network interface auto eth0 iface eth0 inet dhcp
（偶然改为静态ip没有任何区别）
比较我的intel容器和我的arm容器/ run目录是非常稀疏的，只包含lock和systemd （在intel上它包含一个网络子文件夹和许多其他东西）
我猜这个节目（但我真的不知道我在做什么）系统的’启动系统’有问题，无法启动一堆服务。 journalctl返回No journal files were found. 和/ var / log相当稀疏，只包含： pt btmp dist-upgrade dpkg.log fsck landscape lastlog unattended-upgrades wtmp
任何帮助，将不胜感激 ：）
更新：
当我尝试手动运行systemd-journald ，我得到：
qemu: Unsupported syscall: 278 qemu: Unsupported syscall: 74 qemu: Unsupported syscall: 74
更新：
使用更新的qemu版本：
qemu-user-static (1:2.5+dfsg-5ubuntu10.4) to 1:2.6.1+dfsg-0~16.04
来自这个PPA https://launchpad.net/~jacob/+archive/ubuntu/virtualisation
改进了很多东西。 （但还没有ipv4网络）
/ var / run现在填充了预期目录（包括网络）
journalctl现在可以工作并返回：

相关的错误行似乎是Aug 26 18:02:27 ubuntu systemd-udevd[92]: error initializing netlink socket
更新
我尝试使用dhcp和静态配置运行ifup eth0 -v ，并且两种方式都给出了类似的错误：
dhcp Error getting interfaces; Address family not supported by protocol Error getting interfaces; Address family not supported by protocol
static Cannot open netlink socket: Address family not supported by protocol
（由于缺乏声誉而回答。）
我有同样的问题。 lxc容器没有获得IPv4地址。 运行dhclient eth0 -v导致错误消息，幸运的是我带到了这里
获取接口时出错; 协议不支持的地址族
这个post真的救了我的一天。 在构建一个新的qemu二进制文件之后，我可以使用这个默认配置文件使armhf容器加入我的LAN（ eno1是我主机上的以太网接口）：
name: default config: {} description: Default LXD profile devices: eth0: name: eth0 nictype: macvlan parent: eno1 type: nic
我正在使用qemu 2.7.0二进制文件，您可以从源代码编译并安装在一些
./configure --target-list=arm-linux-user --static --prefix= make make install
在启动armhf容器之前，只需在那里获得新的qemu
lxc file push
另一个不错的副作用是我现在可以在没有--force标志的情况下停止容器！
事实certificate，qemu 2.6.1不能很好地工作，以便在一个arm容器中工作。
我将以下3个补丁应用于qemu 2.6.1（在运行apt get source qemu-user-static ）
https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg06203.html https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg06204.html https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg06205.html
和重建（使用debuild ）
然后从deb文件中提取新构建的qemu-aarch64-static并安装到容器/usr/lib/lxd/container/$NAME/rootfs/usr/bin
网络现在有效：
