Are 32-bit applications supported in RHEL 7?
> Issues
- Will Red Hat continue to support 32-bit applications in the future, for example in Red Hat Enterprise Linux 7 ?
- Are 32-bit libraries provided with Red Hat Enterprise Linux distributions?
- Is there a 32-bit DVD ISO to install RHEL 7?
- Can I install RHEL 7 on 32-bit hardware?
- Will RHEL 7 suppport i386 and i686 (x86) or only x86_64?

> Resolution
Red Hat Enterprise Linux 7 will only provide 64-bit ISO's, thus allowing only a 64-bit operating environment. However, 32-bit is supported in the following ways:

- RHEL 7 will continue to provide selected libraries in both 32-bit and 64-bit, allowing 32-bit applications to run in the 64-bit RHEL 7 OS environment. This functionality also exists for RHEL 5 & 6 as documented in the knowledge article: How to install 32-bit packages on a 64-bit system
- RHEL 7 will continue to support the multilib toolchain, allowing applications to be compiled for both 32-bit and 64-bit.
- RHEL 7 can host, using KVM virtualization technology, both 32-bit and 64-bit virtual guest instances of RHEL 5 and RHEL 6.

While RHEL 7 will not natively support 32-bit hardware, certified hardware can be searched in the certified hardware database.
