RVA23 QEMU镜像网络问题解决及相关资源汇总——openEuler RISC-V项目详解

通过排查，可以确定是由于NetworkManager软件包自带的一个配置文件造成的干扰。
usr lib NetworkManager conf.d 00-server.conf
这个文件，在网络正常的设备上没有，在此镜像上，删除后来，重启，网络连接正常。

[root@openeuler-riscv64 ~]# cat  usr lib NetworkManager conf.d 00-server.conf# This configuration file changes NetworkManager s behavior to# what s expected on "traditional UNIX server" type deployments.## See "man NetworkManager.conf" for more information about these# and other keys.[main]# Do not do automatic (DHCP SLAAC) configuration on ethernet devices# with no other matching connections.no-auto-default=*# Ignore the carrier (cable plugged in) state when attempting to# activate static-IP connections.ignore-carrier=*[root@openeuler-riscv64 ~]# rpm -qf  usr lib NetworkManager conf.d 00-server.confNetworkManager-config-server-1.44.2-3.oe2503.noarch
      
在oerv2503的普通镜像(固件不同)下
