Chapter 2. Architectures

Red Hat Enterprise Linux 7.6 is distributed with the kernel version 3.10.0-957, which provides support for the following architectures: [1]
  • 64-bit AMD
  • 64-bit Intel
  • IBM POWER7+ (big endian)
  • IBM POWER8 (big endian) [2]
  • IBM POWER8 (little endian) [3]
  • IBM POWER9 (little endian) [4] [5]
  • IBM Z [4] [6]
  • 64-bit ARM [4]

[1] Note that the Red Hat Enterprise Linux 7.6 installation is supported only on 64-bit hardware. Red Hat Enterprise Linux 7.6 is able to run 32-bit operating systems, including previous versions of Red Hat Enterprise Linux, as virtual machines.
[2] Red Hat Enterprise Linux 7.6 POWER8 (big endian) are currently supported as KVM guests on Red Hat Enterprise Linux 7.6 POWER8 systems that run the KVM hypervisor, and on PowerVM.
[3] Red Hat Enterprise Linux 7.6 POWER8 (little endian) is currently supported as a KVM guest on Red Hat Enterprise Linux 7.6 POWER8 systems that run the KVM hypervisor, and on PowerVM. In addition, Red Hat Enterprise Linux 7.6 POWER8 (little endian) guests are supported on Red Hat Enterprise Linux 7.6 POWER9 systems that run the KVM hypervisor in POWER8-compatibility mode on version 4.14 kernel using the kernel-alt package.
[4] This architecture is supported with the kernel version 4.14, provided by the kernel-alt packages. For details, see the Red Hat Enterprise Linux 7.5.
[5] Red Hat Enterprise Linux 7.6 POWER9 (little endian) is currently supported as a KVM guest on Red Hat Enterprise Linux 7.6 POWER9 systems that run the KVM hypervisor on version 4.14 kernel using the kernel-alt package, and on PowerVM.
[6] Red Hat Enterprise Linux 7.6 for IBM Z (both the 3.10 kernel version and the 4.14 kernel version) is currently supported as a KVM guest on Red Hat Enterprise Linux 7.6 for IBM Z hosts that run the KVM hypervisor on version 4.14 kernel using the kernel-alt package.
