Installing RHEV-M on a system using certificate-based RHN
I was attempting to follow the RHEV-M installation instructions in the RHEV 3.0 Installation Guide, but I got stuck in section 2.2.3.2 (Red Hat Network Configuration) with the "rhn-channel --add ..." commands.
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization/3.0/html/Installation_Guide/Tasks_RHEV_Red_Hat_Network_Subscription.html
These fail with a python traceback:
# rhn-channel --add --channel=rhel-x86_64-server-6-rhevm-3

I'm guessing this may have something to do with the fact that this system (running RHEL 6.2) was registered with the new certificate-based RHN, whereas the instructions seem to assume a system using the older "RHN Classic" method. My understanding is that "channels" no longer exist under the new certificate-based RHN. Can anyone confirm this? Are there updated instructions somewhere that explain how to give a machine access to the RHEV-M software using the new certificate-based RHN?
