• Guest has not been reported on any host and is using a temporary unmapped guest subscription.

Resolution

• A bug has been detected where the RHEL 9 virtual machines are unable to get the virtual subscription SKU from the hypervisors due to subscription-manager not able to collect the system dmidecode data although the hypervisor is subscribed and virt-who is properly configured. The This content is not included.Bugzilla 2094099 has been fixed by the engineering team.

• This issue is now resolved with the following Red Hat Bugzilla Advisory. To fully resolve this issue please update the subscription-manager package to subscription-manager-1.29.30-1.el9.x86_64 or later.

• If the update of the subscription-manager package is not immediately possible, then as a workaround, create a custom rhsm facts file, add the system UUID manually and subscribe the VM. Run below commands in the given order in RHEL 9 VM. Add system UUID taken from # dmidecode | grep -i uuid command in place of xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx.

      # subscription-manager clean
  
      # cd /etc/rhsm/facts
  
      # echo "{\"dmi.system.uuid\":\"xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\",\"virt.uuid\":\"xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\"}" >redhat.facts
  
      # subscription-manager facts | grep -i uuid
  
      # subscription-manager register
  
      # subscription-manager attach --auto
  
      # subscription-manager status

Root Cause

The subscription-manager service doesn't capture the dmidecode information from the server which includes the system UUID in subscription facts. Hence, the subscription-manager is unable to map the UUID to the host-guest mapping collected through the virt-who service to get a derived virtual subscription SKU from the hypervisor.

Diagnostic Steps

• Run below commands and check the subscription status. A temporary SKU is attached to the VM.

   # subscription-manager status
   # subscription-manager list --consumed
