Are 32-bit applications supported in RHEL 7?

Updated 2015-02-08T23:12:37+00:00

Issue

  • 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?

Environment

  • Red Hat Enterprise Linux (RHEL) 7

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 for in the certified hardware database.
