virt-who host-guest mapping on Red Hat Satellite GUI is inaccurate.

Solution Verified - Updated -

Environment

  • Red Hat Satellite 6.3.x
  • Red Hat Satellite 6.4.x

Issue

  • The guest count on the hypervisor profile of Red Hat Satellite GUI is incorrect(and vice versa).

Resolution

  • There is a Bug filed for this behavior where the host-guest mapping is inaccurate on Red Hat Satellite's GUI.

  • Workaround for Sat 6.4.x:

  • Take a backup of the following file:

[root@satellite ~]# cp /opt/theforeman/tfm/root/usr/share/gems/gems/katello-3.7.0.42/app/lib/katello/resources/candlepin/consumer.rb /opt/theforeman/tfm/root/usr/share/gems/gems/katello-3.7.0.42/app/lib/katello/resources/candlepin/consumer.rb.bkp

Note: The katello version for the above file may vary. Use # locate consumer.rb to find the absolute path for this file.

  • Make the following edits:
[root@satellite ~]# vi /opt/theforeman/tfm/root/usr/share/gems/gems/katello-3.7.0.42/app/lib/katello/resources/candlepin/consumer.rb

               includes = params.key?(:include_only) ? "&" + included_list(params.delete(:include_only)) : ""
               fetch_paged do |page_add|
                 response = super(path + hash_to_query(params) + includes + "&#{page_add}", self.default_headers).body
-                JSON.parse(response)                                <<============= Delete.
+               JSON.parse(response).map(&:with_indifferent_access)   <<============= Add.
               end
             end
           end

self.facts = consumer_params['facts'] unless consumer_params['facts'].blank?

         update_hypervisor(consumer_params)
         update_guests(consumer_params)
  • Restart Red Hat Satellite services:
[root@satellite ~]# katello-service restart
  • Restart virt-who to update the host-guest mapping:
[root@satellite ~]# service virt-who restart

Diagnostic Steps

  • Possible affected package versions are:
[root@satellite6.4 ~]# rpm -qa | egrep "satellite-6|candlepin"
candlepin-selinux-2.4.8-1.el7.noarch
satellite-6.4.2-2.el7sat.noarch
candlepin-2.4.8-1.el7.noarch

[root@satellite6.3 ~]# rpm -qa | egrep "satellite-6|candlepin"
candlepin-selinux-2.1.24-1.el7.noarch
satellite-6.3.5-1.el7sat.noarch
candlepin-2.1.24-1.el7.noarch
