It appears you have an issue with the DNS settings of your RHEV Manager. Either they are wrong, or you are unable to reach a nameserver.

  • review your resolv.conf
  • make sure that nsswitch.conf is configured to use DNS
  • try doing a dig of cdn.redhat.com using the nameservers you have defined in /etc/resolv.conf
  • ping google to see if your default route is correct (this may not work on your network though)
cat /etc/resolv.conf
grep ^hosts /etc/nsswitch.conf
for HOST in `grep ^nameserver /etc/resolv.conf | awk '{ print $2 }'`; do dig @${HOST} cdn.redhat.com; done
ping -c3 8.8.8.8

If DNS was previously having issues, you likely were not able to subscribe to the correct channels for RHEV.

Make sure that your host is registered to RHN (or your Satellite). Then..
Look in your installation guide for the section that describe which channels you need for RHEV, similar to the following:

rhn-channel --add --channel=rhel-x86_64-server-6-rhevm-3.3
