Chapter 6 Release-Specific Information for Oracle Linux 8 Update 1 (aarch64)


The following information pertains to the 64-bit Arm (aarch64) platform, which is available as a developer preview release only in Oracle Linux 8.1.

6.1 System Requirements and Limitations (aarch64)

The system requirements and limitations for the 64bit Arm (aarch64) architecture in Oracle Linux 8 Update 1 (aarch64) are currently under review.

6.2 VNC Remote Console Available as Technology Preview on 64-bit Arm Platform

In this update, the Virtual Network Computing (VNC) remote console is available as a Technology Preview only on the 64-bit Arm (aarch64) platform. The remaining components of the graphics stack are unverified on this platform.

6.3 Known Issues (aarch64)

The following are known issues for the Oracle Linux 8 Update 1 (aarch64) release only. See Chapter 4, Known Issues for information about known issues on the x86_64 platform.

6.3.1 Kdump sometimes fails on ThunderX2 and X-Gene 3 platforms

System hangs might occur during a crash kernel boot on ThunderX2 and X-Gene 3 platforms that are running Oracle Linux 8 Update 1 (aarch64). This issue has been observed at different stages of the boot process. Consequently, Kdump might not work as expected on this hardware.

(Bug IDs 30339519, 30339571)

6.3.2 Excessive write activity inside a guest can crash the guest kernel

In an environment where a guest system is performing excessive write activity to /dev/stdout, subsequent repeated suspend and resume operations on the same guest can cause the guest kernel to crash. Furthermore, the guest kernel can also crash when reverts from a snapshot state that had excessive write activity on /dev/stdout to an idle snapshot state occur.

This issue is related to a patch that is present in the guest kernel for the 64-bit Arm platform and is currently under investigation. A fix is likely to be provided in a subsequent errata release.

6.4 Installation and Availability (aarch64)

The following installation and availability information applies specifically to the 64-bit Arm platform for Oracle Linux 8.1.

You can download the Oracle Linux 8 Update 1 (aarch64) release as a developer preview installation media image from the Oracle Technology Network at

The latest Oracle Linux 8 Update 1 (aarch64) packages are available from the Unbreakable Linux Network (ULN) and the Oracle Linux yum server. To explore the channels that are available on ULN, log in to and view the Channels option. Or, you can obtain the latest Oracle Linux 8 (aarch64) packages from the Oracle Linux yum server at

You can use the Oracle Linux 8 (aarch64) ISO image for a standard installation on generic 64-bit Armv8 hardware. The ISO image can be loaded from local media, such as DVD-ROM or USB flash drive; or, you can perform a network-based kickstart installation by using PXE. If you perform a network-based installation and you want to access the graphical interface for the installer, you must change the kernel boot parameters to enable VNC. For example, to enable VNC, set the inst.vnc boot option, and then set the network address to ip=eth0:dhcp at boot.
