In OVH data center, operating systems on servers use local repositories by default. Currently, using these repositories on the server may cause problems when adding the server as a node of the VMmanager cluster.

To change the repositories, perform the following in the files /etc/yum.repos.d/CentOS-Base.repo and /etc/yum.repos.d/CentOS-fasttrack.repo:

  1. Comment out baseurl strings with a link to local repositories.
  2. Uncomment mirrorlist strings with a link to the official list of CentOS repositories.

Example of file /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
