4.7. Multiarchitecture Policy

For the system to support multi-arch packages, such as x86_64, you can install one or both versions of a given package. To determine what to do in general you should define the multilib_policy configuration parameter.

multilib_policy all|best: all means that yum will install all possible architectures of any package you wish to install. Then yum install foo will install foo.i386 and foo.x86_64 in x86_64 systems, if available. best means installing only the best architecture for this platform.
