Sorry, i found the error of my ways… The initial OpenNebula install was from ubuntu repo (not the opennebula repo). And it seems that the ubuntu version uses the next available UID/GUID for oneadmin.
I uninstalled Opennebula, removed oneadmin, updated the sources list to point to correct opennebula repo, and reinstalled. Voila the UID and GUID became 9869.
User Error here…
Hope this thread might help someone else that might make this same mistake in the future.
