Resolution

• The virt-who should be running on a virtual system running on RHEV-H system. On this system confirm that virt-who package is installed using rpm -q virt-who. If package is not installed then temporary register this virtual system to portal using below commands and install virt-who package.

  # subscription-manager register
  # subscription-manager attach --auto
  # yum install `virt-who`
  

• After installing package successfully unsubscribe system as its virtual system and without virt-who it would be consuming physical subscription,

  # subscription-manager unsubscribe --all
  

• Run subscription-manager identity command and note down org ID.

• Configure virt-who options in /etc/sysconfig/virt-who file:

  # Register guests using RHEV-M
  VIRTWHO_RHEVM=1
  VIRTWHO_DEBUG=1
  #Options for RHEV-M mode
  VIRTWHO_RHEVM_OWNER=<org ID noted in previous step>
  VIRTWHO_RHEVM_ENV=Library
  VIRTWHO_RHEVM_SERVER=<your.rhevm.com:port>
  VIRTWHO_RHEVM_USERNAME=<rhevm-user@rhevm-domain>
  VIRTWHO_RHEVM_PASSWORD=<rhem-user-password>
  

  • Make changes in <org ID noted in previous step>,<your.rhevm.com:port>,<rhevm-user@rhevm-domain>,<rhem-user-password> as per environment. In <your.rhevm.com:port> port number is mandatory and by default it is 443. In case of any issues with port 443 then confirm port number from RHEV-M administrator.

• Start virt-who service using,

  On RHEL 5,6,
  # service virt-who start
  
  On RHEL 7,
  # systemctl start virt-who.service
  

• Logs for the virt-who service can be seen in /var/log/rhsm/rhsm.log log file.

• Once this is all done hypervisor profiles should appear at this link alongside registered system(Hypervisor names appears in alphanumeric characters).

• Once done, attach Virtual Datacenter subscription to the host/hypervisor. After this virtual systems should see the unlimited guest pool, confirm it and subscribe virtual system to virtual subscription using below commands,

  # subscription-manager list --available
  # subscription-manager subscribed --auto
