   name=OpenDaylight Repository
   baseurl=https://nexus.opendaylight.org/content/repositories/opendaylight-yum-epel-6-x86_64/
   gpgcheck=0

   Copy to Clipboard Toggle word wrap

2. 将 上的存储库文件复制到镜像中：

   $ virt-customize --selinux-relabel -a overcloud-full.qcow2 --upload opendaylight.repo:/etc/yum.repos.d/
   [  0.0] Examining the guest ...
   [ 12.0] Setting a random seed
   [ 12.0] Copying: opendaylight.repo to /etc/yum.repos.d/
   [ 13.0] Finishing off
