Product Highlights

Oracle Linux now includes the latest Linux kernel with UEK 8
Oracle has released Unbreakable Enterprise Kernel 8 (UEK 8), the latest version of its optimized Linux kernel, delivering major innovations in memory management, file systems, networking, and platform support. Built on the upstream long-term stable kernel and refined through the UEK-next project, UEK 8 is engineered for high-performance, enterprise-grade workloads on Intel, AMD, and Arm architectures. It supports critical Oracle environments like Oracle Database, Exadata, and Oracle Cloud Infrastructure (OCI), and continues Oracle’s commitment to open, enterprise-ready Linux.

Oracle Linux 9.5 meets USGv6-r1 standards and receives IPv6 Ready Gold Logo
Oracle Linux 9.5 with UEK R7U3 has earned the IPv6 Ready Gold Logo after passing extensive interoperability testing at UNH-IOL. It is the first Enterprise Linux 9.5 host to pass IPv6-Only Functional testing under the USGv6-r1 profile, aligning with U.S. government IPv6 standards set by NIST. These accreditations confirm Oracle Linux 9.5’s readiness for secure, compliant deployment in both government and commercial IPv6 environments.
Read the blog post for more information on USGv6-r1 and the IPv6 Ready Logo.
Leapp open source project provides in-place upgrades for OpenELA-compatible systems
OpenELA has announced a new branch of the Leapp open source upgrade tool, expanding support for all Enterprise Linux variants. Leapp helps users upgrade OS versions safely by identifying risks, automating steps, and verifying compatibility. New enhancements include SELinux and FIPS mode support, network storage compatibility, and kexec fast reboots. Previously limited to Oracle Linux, these features are now shared with the broader OpenELA community, promoting vendor-neutral, enterprise-grade upgrade solutions for RHEL-compatible distributions.
In the press release you will find the details.

Developers Corner

Introduction to PCI Express advanced error reporting
Peripheral Component Interconnect Express (PCIe) error messages can be confusing and technical, often causing unnecessary concern. To interpret them properly—especially terms like "Correctable Errors"—one needs to understand the PCIe architecture, including how devices communicate via point-to-point links composed of lanes.
This blog introduces the basics of PCIe and explains how the Advanced Error Reporting (AER) feature helps detect and report issues. It also discusses how the Linux kernel supports AER and how users can interact with it for better error diagnosis and management.
adaptived—a simple cause-and-effect daemon
adaptived is a lightweight, powerful, and easy to use cause-and-effect daemon that that enables users to create custom automation rules for managing tasks, resources, and system behavior. Building on adaptivemm and oomd, adaptived supports a wider range of technologies through a plugin-based architecture and extensible schema.
See the blog for a comprehensive explanation.
QEMU live updates
Live update is a method for upgrading a QEMU instance and its guest with minimal downtime and no loss of external connections—more efficient than live migration but limited to the same host. It’s now available via cpr-reboot mode in QEMU 8.2 and the upcoming cpr-transfer mode in QEMU 10.0.
