How to register multiple Content Hosts with same UUID to Red Hat Satellite 6.5?

Solution Verified - Updated -


  • Red Hat Satellite 6.5.


  • How can I register multiple machines which have the same UUID (BIOS/Motherboard ID) to Red Hat Satellite 6.5?
  • Experiencing following error while trying to register Content Hosts with the same UUID to Red Hat Satellite 6.5:
HTTP error (500 - Internal Server Error): Multiple profiles found. Consider removing XXX which match this host.


  • A system's UUID is a motherboard product UUID, which is set by the hardware vendor and is encoded into the BIOS and should always be unique.

  • However, if the hardware manufacturer for some reason has set the same UUID for multiple machines you will have to create a custom fact for every machine in order to register them as separate entities with Red Hat Satellite 6.5:

# vi /etc/rhsm/facts/uuid.facts 
{"dmi.system.uuid": "customuuid"}

* customuuid = hostname which is unique for every machine.

Root Cause

  • subscription-manager when trying to register a Content Host to Red Hat Satellite 6.5 looks for the dmi.system.uuid parameter which should be unique.
  • Creating a custom fact at /etc/rhsm/facts/ on the Content Host takes precedence over subscription-manager facts.
