RHN beta channels related to the RHEV-M product have an incorrect architecture: they are listed as x86_64 but it should be IA-32/i386. The arch is also present in the channel labels (and their corresponding families) which is inconsistent and we'd like it to be fixed.

The channel labels that need to change are:
rhev-x86_64-m-d-2-beta ---> rhev-i386-m-d-2-beta
rhev-x86_64-m-s-2-beta ---> rhev-i386-m-s-2-beta

and the family labels that need to change are exactly the same:
rhev-x86_64-m-d-2-beta ---> rhev-i386-m-d-beta-2
rhev-x86_64-m-s-2-beta ---> rhev-i386-m-s-2-beta

These changes need to be replicated in stage and prod environments too.

We did this a while ago for the GA channels but skipped the beta ones because they had content in them and we didn't want to disrupt the beta program. RHEV is not in a beta program right now, so we have time to fix them. This change can't be accomplished using the RCM tooling, because the channel/family label is the *id* those tools work with.  Therefore, it must be done with SQL run against the DB.

My guess of the right SQL to run is below. I HAVE NOT VERIFIED THIS because I do not have DB access to any of the RHN environments.

update rhn.rhnchannel c
   set c.label = 'rhev-i386-m-d-2-beta'
 where c.label = 'rhev-x86_64-m-d-2-beta';

update rhn.rhnchannel c
   set c.label = 'rhev-i386-m-s-2-beta'
 where c.label = 'rhev-x86_64-m-s-2-beta';

   set cf.label = 'rhev-i386-m-d-2-beta'
 where cf.label = 'rhev-x86_64-m-d-2-beta';
