SAM / Virtual Datacenter licenses only

I currently purchased virtual datacenter licenses and i was trying to get SAM working.

I spun up a RHEL 6 server with SAM (via ISO).
I registered the server using rhn classic.

I also installed virt-who on this server.

I have since ran into numerous problems.
i tried to use a combination of this: https://access.redhat.com/articles/480693
which suggests i can register with rhn classic, do what i need to do, and then register with RHSM.

the only difference i'm attempting is to use SAM instead of going directly to the Red hat network.

anyone else try this? is this crazy?
