This is the last part of a long term optimization work, thanks to it a full internet fib , routes based on a pull in January can be pushed to the kernel in 4.

Linux MSC. Linux SCI. Rate this project. Red Hat, Inc. In the third update to Red Hat Enterprise Linux 5, customers will receive a wide range of enhancements, including significantly increased virtualization scalability, expanded hardware platform support and incorporation of OpenJDK Java technologies.

Red Hat uses strict trademark rules to restrict free re-distribution of its officially supported versions of Red Hat Enterprise Linux, but still freely provides its source code. Third-party derivatives can be built and redistributed by stripping away non-free components. DistroWatch Gallery. It brings new features and improvements to help streamline deployments, optimize performance and help mitigate risk in your environments. RHEL 8.

This release brings tooling that will add flexibility and reduce friction in running Podman in a wider range of environments. You can use the Podman container image to help develop and run other container images. Verify container image signatures by default - in RHEL 8.

Existing Red Hat customers can get the new release from the company's Customer Portal , while potential new users can download and try the day evaluation edition. The new development release is built from CentOS Stream. It finishes the migration from Python 2 to Python 3. The new beta also offers smaller binaries due to link time optimization. As a result, applications have smaller and faster binaries and allow deeper inspection of source code at compile time. With Go 1. Additionally, there are also several other improvements and performance optimizations.

The new beta release is available through the Red Hat customer portal. This version introduces new Ansible roles and provides live kernel patching options through the web administration console: " RHEL's web console, based on the upstream Cockpit project, is a web-based interface for managing and monitoring your systems. Enhanced web console performance metrics: The enhanced performance metrics page can help identify potential causes of high CPU, memory, disk, and network resource usage spikes.

In addition, customers can more easily export metrics to a Grafana server. Kernel live patching management via web console: This new web console capability provides a simplified interface for applying live kernel updates without having to use command line tooling.

As always, existing Red Hat customers can get the new release from the company's Customer Portal , while new users can apply to download a day evaluation edition.

Delivered as part of the predictable, six-month cadence of RHEL releases 8. With RHEL 8. With 8. Read about the improvements in Ben Breard's post on new edge features for 8. Red Hat has published a beta for the upcoming release of version 8. In this update, the hypervisor has been updated to automatically set these values to a default of 32GB, which resolves this issue. Due to technical problems with passing TX checksum offload information between paravirtual domains, the use of TX checksum offload in conjunction with NAT for traffic originating from another domain is not supported.

Note that this also applies to fully virtualised domains using paravirtual network drivers. Fully virtualised domains using fully virtualised drivers are not affected as they do not support TX checksum offload at all. Known Issues. Previous versions of the 5.

This note was included by error, and does not apply to Red Hat Enterprise Linux 5. Consequently, kdump may hang waiting for IDE drives to be initialized. In these cases, it is recommended that IDE disks not be used with kdump.

Improvements have been made to the 'nv' driver, enhancing suspend and resume support on some systems equipped with nVidia GeForce and series devices. As such, some package lists e. Optional Packages list in pirut may not display names in alphabetical order. The Hypervisor outputs messages regarding attempts by any guest to write to an MSR. These messages can be safely ignored; furthermore, they are rate limited and should pose no performance risk. To do so, run the following commands:. You can do this by subscribing to the "Productivity App" child channel in Red Hat Network and running the following command:.

If jumbo frames are enabled on your system, a kernel panic will occur if you attempt to unload the bnx2 module. Red Hat advises that you avoid removing a block device from a guest while the device is in use. Doing so causes Xend to lose domain information for the guest. When this occurs, no XII applications can receive keyboard or mouse input. Log in as the affected user or root and run killall -9 nm-applet.

Your system should be able to receive keyboard and mouse input, although Red Hat recommends that you logout and login again to allow the system to fully recover. To workaround this issue, switch to using the other VGA connector on the dongle.

It has been determined that byte objects in kernel slab may be lost when a call to pipe fails. The problem occurs because pipe allocates pipe files, and then tries to get free file descriptors for them.

If the process is out of file descriptors, pipe fails, but it does not clean up properly. A fix for this problem is planned for a forthcoming 5. This issue has been observed with multipathd in particular. For example, if there are LUNs with 8 paths each, the line to be added to the defaults section of multipath.

The libcmpiutil-devel package depends on tog-pegasus-devel , which for the Red Hat Enterprise Linux Desktop product is only available from the Workstation option. Therefore, any attempt to install the libcmpiutil-devel package on a system that does not have a Subscription including the Workstation option or is not subscribed to the Workstation channel on the Red Hat Network, will fail with an unresolved dependency error.

It is possible in rare circumstances, for makedumpfile to produce erroneous results but not have them reported. This is due to the fact that makedumpfile processes its output data through a pipeline consisting of several stages.

If makedumpfile fails, the other stages will still succeed, effectively masking the failure. Should a vmcore appear corrupt, and makedumpfile is in use, it is recommended that the core be recorded without makedumpfile and a bug be reported. An issue may be encountered when using system-config-cluster to configure a Postgres 8 resource agent, resulting in the postgresql service failing to start.

To include a Postgres resource agent in your cluster, please check the man page for the agent, and edit the cluster. Due to outstanding driver issues with hardware encryption acceleration, users of Intel WiFi Link , , , , and wireless cards are advised to disable hardware accelerated encryption using module parameters.

If multiple items are added at the same time, several sequential restarts may be encountered. This behavior is intentional, as it minimizes the time-frame where a crash may occur while memory or processors are not being tracked by kdump.

Technology Previews. This capability is provided as a technical preview in Red Hat Enterprise Linux 5.
