Well, going with Fedora would at least get you the snapshots working, if I remember correctly, but that's not something you run in production. As you said, "major issues".

For CentOS, you need "special" versions of certain packages, since RedHat wants you to pay for RHEV, they have chosen to cripple the standard packages so those features won't work:

And here you can find the packages you need:
