I've been failing to sync oVirt stuff running oVirt today. 
Specifically, the ovirt-appliance-master-el7, though others have failed to.
On another laptop (from the same network though), I'm failing later, when trying to install 'yum-utils':
+ yum install '--disablerepo=*' --enablerepo=alocalsync -y yum-utils
http://192.168.204.1:8585/el7/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Trying other mirror.
