Hi Sando,
Today we've issued a dependency issue where openvswitch-0:2.7.0-1.el7.x86_64
requires python2-six. It seems that this dependency issue was fixed in openvswitch-1:2.7.1-1.1fc27.el7.x86_64.
But the problem is that when querying the centos-ovirt-4.2 repo with dnf I can see the new package, but when querying the same repo for the same package with yum from a centos host, the package can't be seen, thus our CI mirrors can't be updated.
