RedHat sessions roadmap and RedHat 7 new features
The presentations and videos from Red Hat's in-house conference provide information on current and forthcoming products from the open source specialist, including version 7 of Red Hat Enterprise Linux.
Red Hat Enterprise Linux (RHEL) 7 will be based on Fedora 18, which is due for release in November and the first public beta of RHEL 7 is scheduled for sometime in the first half of 2013. The open source specialist provided these and several other details of upcoming and planned new products at Red Hat Summit and JBossWorld 2012, its in-house conference held in Boston in the last week of June.
There are, however, still various details to be fleshed out in the plans for the next generation of RHEL. On Btrfs, for example, Red Hat manager Jim Totten told The H's associates at heise Open that they are watching the development of the filesystem and will offer support in RHEL when it is ready. Btrfs is still marked as experimental in the kernel.org Linux kernel, but has been supported in SUSE Linux Enterprise (SLE) and RHEL derivative Oracle Linux since the spring. Btrfs can be used in RHEL 6, but is marked as a technology preview, meaning that Red Hat takes no responsibility if it blows up in the user's face.
Source: Red Hat The "Red Hat Enterprise Linux Roadmap Highlights" presentation revealed that RHEL 7 will support ext4, XFS and Btrfs for both data and boot partitions. Whether ext4 will remain the default filesystem or be supplanted by Btrfs is unclear. The presentation slides include further information on enhancements planned for the next generation of RHEL. Version 7 should, for example, fully support Linux containers (LXC) – these are, and will remain, a technical preview in RHEL 6. No specific plans for ARM support in RHEL were officially presented, but Red Hat staff have pointed out that Fedora already runs on ARM. Red Hat is also reported to be working with Linaro to improve Java performance on ARM.
The presentation also discussed some of the changes that have found their way into the recently released RHEL 6.3 and RHEL 5.8, as well as some of the updates planned for RHEL 5.9 and 6.4. The highly informative presentation, in which various Red Hat managers elucidate the new features in their areas, is available as two 50 minute long videos.
Burke then has his team of engineering development managers highlight their technology area and key initiatives. They also discuss emerging technologies targeted for delivery in future releases.
Burke first gives a brief Red Hat Enterprise Linux life cycle overview, and an explanation of various themes within Linux development today. He then explores timeframes and Red Hat Enterprise Linux 7 feature possibilities and Fedora 18 enhancements.
He then turns the session over to his teams, who present technology area highlights, including information about:
- kernel and virtual memory
- hardware enablement
- storage and volume management
- filesystem and Gluster
Tim Burke, vice president of Linux Engineering at Red Hat, briefly summarizes the first half's content, then has a team of engineering development managers highlight their technology area and key initiatives. They also discuss emerging technologies targeted for delivery in future releases.
Areas they discuss in this part include:
- base OS commands and util
- desktop features
- developer tool features
RedHat enterprise virtualization:
Dubuque discusses the current environment, including virtualization competitor VMware, and the opportunity that a second source for virtualization--a open standards source--offers.
He then offers details about Red Hat Enterprise Virtualization, including information about management features, hypervisor technology, specVIRT success, and opportunities for cost savings.
Cathow then joins in to talk about development of Red Hat Enterprise Virtualization 3 and 3.1, and the growth of the communities surrounding it, including Fedora and oVirt.
Cathow highlights features and changes in Red Hat Enteprise Virtualization, including:
- OpenJDK requirement for proprietary Oracle JRE is eliminated.
- Support for Jasper 4.7 and two new directory servers
- Scalability to 160 Virtual CPUs per VM and 2T virtual RAM per VM
- enhanced physical to virtual migration (P2V)
- Live snapshots
- Shared disks
- SDK availability
- new top-level manager for managing disks
- direct LUN access
Cathow details many other system and version features, including a overview of key technologies for future versions of Red Hat Enterprise Virtualization and Red Hat Enterprise Linux. He also intermittantly takes questions from the audience.
