==> ps-vagabond:  One of the configured repositories failed (Latest Unbreakable Enterprise Kernel Release 3 for Oracle Linux 7Server (x86_64)),

==> ps-vagabond:  safe thing yum can do is fail. There are a few ways to work "fix" this:
==> ps-vagabond:
==> ps-vagabond:      1. Contact the upstream for the repository and get them to fix the problem.
==> ps-vagabond:
==> ps-vagabond:      2. Reconfigure the baseurl/etc. for the repository, to point to a working
==> ps-vagabond:         upstream. This is most often useful if you are using a newer
==> ps-vagabond:         distribution release than is supported by the repository (and the
==> ps-vagabond:         packages for the previous distribution release still work).
==> ps-vagabond:
==> ps-vagabond:      3. Disable the repository, so yum won't use it by default. Yum will then
==> ps-vagabond:         just ignore the repository until you permanently enable it again or use
==> ps-vagabond:         --enablerepo for temporary usage:
==> ps-vagabond:
==> ps-vagabond:             yum-config-manager --disable ol7_UEKR3
==> ps-vagabond:
==> ps-vagabond:      4. Configure the failing repository to be skipped, if it is unavailable.
==> ps-vagabond:         Note that yum will try to contact the repo. when it runs most commands,
==> ps-vagabond:         so will have to try and fail each time (and thus. yum will be be much
==> ps-vagabond:         slower). If it is a very temporary problem though, this is often a nice
==> ps-vagabond:         compromise:
==> ps-vagabond:
==> ps-vagabond:             yum-config-manager --save --setopt=ol7_UEKR3.skip_if_unavailable=true
==> ps-vagabond:
==> ps-vagabond: failure: repodata/primary.xml.gz from ol7_UEKR3: [Errno 256] No more mirrors to try.

To manually resolve the issue, I updated the /etc/yum.repos.d/public-yum-ol7.repo by hand. This was in version 0.0.4 of the vagrant box.

[iversond]

sudo rm /etc/yum.repos.d/public-yum-ol7.repo
cd /etc/yum.repos.d
wget http://public-yum.oracle.com/public-yum-ol7.repo

I wasn't able to get a re-creation case on this, but I think it may be related to the recent transition of OEL 7.2 to 7.3. I experienced an almost identical error when trying to provision a CentOS 7.2 VM.

At any rate, I went ahead and upgraded the Vagrant box to use OEL 7.3 - so running vagrant box update should upgrade bring it up to date.
