Issue

  • rhn_register fails for vmware and hyper-v guests with "Red Hat Enterprise Linux as a Virtual Guest"
  • Virtual system is consuming physical entitlement.

Resolution

This issue should be fixed in the current version. If you encounter this issue, make sure you are running at least RHEL 5.4, RHEL 4.8, or RHEL 3.9 on the guest. If not, you will need to update.

If you are still getting this issue with the latest version, you likely don't have all of the updates. You will need to update the following packages to make this work:

  • rhnlib
  • rhn-setup
  • rhn-client-tools
  • dmidecode
  • python-dmidecode
  • hal

  • yum (or up2date)

  • +dependencies

Root Cause

  • RHN cannot tell that RHEL (Versions 5.3, 4.7, 3.8 and below) is running as a virtual guest on VMware, Hyper-V or Hitachi and thus does not know to request flex entitlements. Since the SKU has only flex entitlements, rhn_register attempts to grab regular entitlements and fails if none are available.
