Solution Verified - Updated -

Environment

  • Red Hat Satellite 6
  • virt-who

Issue

  • virt-who is failing to function correctly and is displaying the following error message:

  • virt-who is unable to report the hypervisor and is encountering the following error:

        virt.py:_send_data:609 - Error during heartbeat: Communication with subscription manager failed with code 302:Unknown content error (HTTP 302 - Found, len 0)

Resolution

  • Execute the following command on the virt-who server to exclude it from using the proxy:

     # subscription-manager config --server.no_proxy=satellite-fqdn-name

Diagnostic Steps

  • Upon checking the rhsm.log, it was found that the system was using a proxy. Even after setting no_proxy=* in /etc/virt-who.conf and adding no_proxy=* in rhsm.conf, virt-who still used the proxy.
