当用virt-manager命令启动VM 管理工具是报错:vm manager failed to contact configuration server

如下办法解决了我的问题:

读取dbus uuid

dbus-uuidgen --get

查看旧的uuid

cat /var/lib/dbus/machine-id


重新创建uuid

dbus-uuidgen > /var/lib/dbus/machine-id  <uuid>


[root@VM-4-6-centos usr]# yum makecache # 生成新缓存 Loaded plugins: fastestmirror, langpacks Repository centos-sclo-rh is listed more than once in the configuration Repository epel is listed more than once in the configuration Determining fastest mirrors Could not retrieve mirrorlist http://mirrorlist.centos.org?arch=x86_64&release=7&repo=sclo-sclo error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Name or service not known" One of the configured repositories failed (Unknown), 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=<repoid> ... 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 <repoid> or subscription-manager repos --disable=<repoid> 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: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: centos-sclo-sclo/x86_64 国内镜像已经更新,还是出错
