Hi,
with upcoming CentOS 1708 all the SIGs have been asked to do some cleanup of old / unsupported stuff.
As part of the cleanup, ovirt 3.5, 3.6 and 4.0 will be dropped from http://mirror.centos.org/centos/7/virt/x86_64/

Also, as part of the cleanup a few packages previously tagged in CentOS VIrt SIG repos and now available in CentOS base / optional / extras repo have been untagged and won't be in http://mirror.centos.org/centos/7/virt/x86_64/ when the repo will be re-generated from tags.
As a side effect, you may see cockpit related packages not available if you're running oVirt on RHEL 7.4 instead of CentOS 7.1708 because on CentOS 7 extras channel is enabled by default while on RHEL you need to enable it manually.

Thanks,
