</div>Could I ask what the use case is for i386 support? I know that the pointers are smaller but memory is cheap. Is this a speed or a hardware or a can it be done goal?<br>

Especially in cloud where you might be firing up a thousand hosts at a time.</div>
<div>2) Multiple Virtual Machines don't do well in the transition from 32 bit to 64 bit in that their memory usage doesn't go up by *2 but can be ^2 depending on the workload. Python is a perfect example of this but there are cases in java and other 'virtual machine' environments where it happens.</div>
<div>3) As nice as having i686 compat libraries are for some commercial apps you end up needing a lot more than what is provided by the OS. This really comes up when you have to run a mixed set of commercial binaries that need something that only EL7 provides but also needs stuff that EL6 had. Thus you end up needing i686 everything.</div>
