Satellite 6 : virt-who fails with gaierror: [Errno -2] Name or service not known

Environment

Red Hat Satellite 6
virt-who

Issue

In satellite 6, the virt-who failed to start with the below error:

gaierror: [Errno -2] Name or service not known
MainProcess(111282):MainThread @executor.py:terminate:222 - virt-who is shutting down

Resolution

• Check virt-who configuration file from /etc/virt-who.d/x.conf and make sure the rhsm_hostname is not specified with "https://satellite-hostname".
  rshm_hostname in the virt-who configuration file should be only hostname not Content from hostname is not included.https://hostname/

for example:

rhsm_hostname=https://satellite.hostname

Instead it should be :

rhsm_hostname=satellite.hostname

For more KB articles/solutions related to Virt-who and Virtual Datacenter (VDC) Subscriptions Issues, please refer to the Consolidated Troubleshooting Article for Virt-who and Virtual Datacenter (VDC) Subscriptions Issues

Root Cause

The value specified in rhsm_hostname, counted as a FQDN .

So as a result, when we specify "https://satellite-hostname" , the full value including 'https' is counted as hostname. As a result it fails to resolve this name.

Diagnostic Steps

$ more rhsm.log :
