Установил центос, и сразу yum update, и сразу выхлоп:
Загружены модули: fastestmirror
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra... error was
14: curl#56 - «Recv failure: Соединение разорвано другой стороной»
One of the configured repositories failed (Неизвестно),
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

При первом старте системы заметил FAILED.. repo.. не успел прочитать, в логах не смог найти. Месяц на никсах, ток учусь.
помимо этой виртуалки установлено еще две, тоже центос, все работает.
Проблема решилась настройкой виртуалки. За место сетевого моста поставил нат. Но вопрос не закрыт, тк другие виртуалки работают по сетевому мосту.
И последний update. После yum update/upgrade через NAT, сменил на сетевой мост, репозитории заработали. Пинг дублируется из-за как-раз сетевого моста. Всем спасибо, вы отличные собеседники.
