oerv的pretask3

任务三：尝试使用 qemu user & nspawn 或者 docker 加速完成任务二
如果前面使用了从qemu提取出来根文件系统，那么直接chroot进入这个根文件系统即可。否则，就跳转到后面的内容吧。
root@yyjeqhc:~# pwd
/root
root@yyjeqhc:~# ls
chroot git oe2503_qemu qemu_oe2503_rootfs snap unmount
./chroot
IP address: 192.168.126.103
IP address: 100.92.192.51
IP address: 172.17.0.1
Users online: 0
#直接就能进入系统。
#但是需要手动修改/etc/resolv.conf，因为是直接从qemu复制过来的，所以有些配置需要逐一修改。
curl 4.ipw.cn
#确保网络正常，然后剩下的操作，和pretask2的一样，配置osc等。
#还是构建pcre2吧，结果如下：

#快了一半。
这样的话，pretask3就结束了。
但是，不妨比较一下多种加速方式的区别。

The buildroot was: /var/tmp/build-root/standard_riscv64-riscv64
Cleaning the build root may fix the problem or allow you to start debugging from a well-defined state:
- add '--clean' option to your 'osc build' command
- run 'osc wipe [--vm-type=...]' prior running your 'osc build' command again
#这个就是容器里面没有ipv6的dns解析服务（没有运行在本地的ipv6 dns服务器）
dnf install -y dnsmasq
vim /etc/dnsmasq.conf
#添加下面两行即可
listen-address=127.0.0.1,::1
server=172.17.0.1
[root@679d595cbbfe Kmesh]# dnsmasq --test

然后就可以正常下载了go代码了。
#当然了，只是解决dial tcp: lookup repo.huaweicloud.com on [::1]:53: read udp [::1]:56271->[::1]:53: read: connection refused，解决了解析失败的问题。
#包构建失败的原因还是需要具体分析。
网络问题解决，构建过程就正常了。

#构建失败和官网上的日志是一样的
回到chroot里面，构建Kmesh这个包也会出一样的问题，解决方案是修改主机的dns服务
root@yyjeqhc:~# netstat -tlnp |grep 53

vim /etc/systemd/resolved.conf
#查看配置内容，然后在指定位置添加下面两行即可，然后重启解析服务
[Resolve]

DNSStubListenerExtra=::1
root@yyjeqhc:~# systemctl restart systemd-resolved
Warning: The unit file, source configuration file or drop-ins of systemd-resolved.service changed on disk. Run 'systemctl daemon-reload' to reload units.

#然后，chroot里面再构建，就不会出现这个错误了。会正常构建到最后失败
最后，试一下主机环境，即ubuntu直接安装osc构建工具
