VMware所有虚拟机桥接无法联网

VMware所有虚拟机桥接无法联网

打开虚拟机，突然发现yum更新报错：
[root@samba~]# yum -y install samba
已加载插件：fastestmirror, langpacks
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - “Could not resolve host: mirrorlist.centos.org; 未知的错误”
One of the configured repositories failed (未知),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:

1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
   upstream. This is most often useful if you are using a newer
   distribution release than is supported by the repository (and the
   packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
   yum --disablerepo= …
4. Disable the repository permanently, so yum won’t use it by default. Yum
   will then just ignore the repository until you permanently enable it
   again or use --enablerepo for temporary usage:
   yum-config-manager --disable
   or
   subscription-manager repos --disable=
5. Configure the failing repository to be skipped, if it is unavailable.
   Note that yum will try to contact the repo. when it runs most commands,
   so will have to try and fail each time (and thus. yum will be be much
   slower). If it is a very temporary problem though, this is often a nice
   compromise:
   um-config-manager --save --setopt=.skip_if_unavailable=true
   Cannot find a valid baseurl for repo: base/7/x86_64

昨天还正常使用的虚拟机今天不能联网，也无法ping通其他机子，查看配置显示如下，配置是正确的：

打开虚拟网络编辑器：

还原配置：

还原后如下所示：

重新启动虚拟机查看联网情况，发现还是不能联网。

最后解决方法：

1. 打开本机的网络中心，查看网卡名称：
   
2. 修改VMware桥接网络配置：
   
   重启虚拟机网络，正常了！！！
