Red Hat Virtualization Manager Requires Windows

"As a major Linux vendor, one might expect that Red Hat's new Red Hat Enterprise Virtualization for Servers solution would be able to run on Linux servers. You'd be wrong. Not only is that not the case, but the Management Server piece of RHEV, which provides virtualization management capabilities, requires users to be running Microsoft's Windows Server. That's no typo: A Linux vendor is requiring its users to run one of its key new products on the rival, closed source Windows operating system. According to Red Hat, the plan is to have a Linux version ready by some point in 2010. But in the meantime, Red Hat customers who want to run the virtualization manager must purchase or already own a Windows server."

CentOS 5.4 Released

The fourth update in the CentOS Linux 5 family is released. Highlights of the new release include a kernel-based virtual machine virtualization, alongside of Xen virtualization technology. The scalability of the virtualization solution has been incremented to support 192 CPUs and 1GB hugepages, GCC 4.4 and a new malloc(), clustered, high-availability filesystem etc. Grab a CD set from a mirror, and via BitTorrent 32bit, 64bit DVD. On a related note, if you are already running CentOS-5.3 or an older CentOS-5 distro, simply upgrade it over the Internet.

Red Hat Enterprise Linux 5.4 Released

The fourth update in the Red Hat Enterprise Linux 5 family is released. From the press release: this version includes kernel-based virtual machine virtualization, alongside of Xen virtualization technology. The scalability of the Red Hat virtualization solution has been incremented to support 192 CPUs and 1GB hugepages. Other updates including GCC 4.4 and a new malloc(), clustered, high-availability filesystem to support Microsoft Windows storage needs on Red Hat Enterprise Linux. Also, support for technologies such as FCoE for storage environments and SR-IOV to improve virtual I/O performance and management included.

Update: CentOS/Lance Davis Situation Resolved

It looks like the CentOS leadership situation is moving towards a resolution: "The CentOS Development team had a routine meeting today with Lance Davis in attendance. During the meeting a majority of issues were resolved immediately and a working agreement was reached with deadlines for remaining unresolved issues. There should be no impact to any CentOS users going forward. The CentOS project is now in control of the CentOS.org and CentOS.info domains and owns all trademarks, materials, and artwork in the CentOS distributions. We look forward to working with Lance to quickly complete all the agreed upon issues. More information will follow soon."

Red Hat Enterprise Linux 5.4 Beta Released

"Red Hat today officially announced the beta availability of Red Hat Enterprise Linux 5.4, which in my view is a lot more than a typical point release. Sure we're all waiting for the big RHEL 6 release, but there are some major changes in RHEL 5.4. The most obvious change is the shift to the KVM hypervisor (as opposed to Xen). Xen is still in RHEL, but with RHEL 5.4, Red Hat is signaling its intention that KVM (eventually) is to be Red Hat's preferred Hypervisor. It's a preference that Red Hat execs have indicated at multiple points this year and should be no surprise since Red Hat now owns lead KVM vendor Qumranet."

Red Hat CEO Calls on Oracle to Keep Java Open

"With Oracle set to acquire Sun and gain stewardship over Java, there are many in the tech world with an opinion on how the database giant should handle its new relationship with the programming language. One of those opinions is being voiced by Red Hat CEO Jim Whitehurst, who is calling on Oracle to keep Java open. During a conference call yesterday to discuss Red Hat's first-quarter fiscal 2010 results, Whitehurst also took aim at Oracle's operating system business."

‘Risk report: Four years of Red Hat Enterprise Linux 4’

Mark Cox, Red Hat's director of security response, has published his usual risk report, which includes very detailed statistics and other information on security issues and how they were handled in Red Hat Enterprise Linux 4. Red Hat remains the only OS vendor to directly publish such information and provide the raw data as well. "Red Hat is continually developing technologies to help reduce the risk of security threats, and a number of these were consolidated into Red Hat Enterprise Linux 4. The most significant technologies were SELinux and Exec-Shield. Exec-Shield is a project which includes support for the No eXecute (NX) memory permission, simulating NX via segment limits, Position Independent Executables (PIE), gcc, and glibc hardening. For more details, a table of the major security technology innovations in Enterprise 4 is available."

Red Hat’s JBoss Software Draws Patent Suit

InformationWeek reports that Red Hat is being sued for patent infringement by Software Tree. The patent involved is of an impedance-matching layer between an object-oriented system and a relational database. "Red Hat acquired open source developer JBoss in 2006 for $420 million. Software Tree contends that certain of Red Hat's JBoss products, including the JBoss Enterprise Application Platform, which includes JBoss Hibernate, step on its patent. 'The infringing products have no substantial noninfringing uses,' Software Tree says in court papers. The lawsuit also names Dell, Hewlett-Packard, and Genuitec as defendants because the companies sell JBoss-based software or include it on their products." This is not the first time Red Hat has been sued over JBoss technology. A previous suit was the first public GPL compatible patent settlement and protected not only Red Hat but downstream users and developers as well.

Microsoft, Red Hat Team up on Patent-Free Interoperability

For years, Microsoft has insisted that open-source vendors acknowledge that its patent portfolio is a precursor to interoperability discussions. Monday, Microsoft shed that charade and announced an interoperability alliance with Red Hat for virtualization. Red Hat has long argued that patent discussions only cloud true interoperability, which is best managed through open source and open standards. Now it has got what it wanted; unlike the Novell-Microsoft agreements, there is no exclusionary patent deals or cross payments.

Red Hat Snaps up Mandriva’s Adam Williamson

Adam Williamson, who was let go from Mandriva at the end of last year, has announced that he has been hired by Red Hat as a Senior Quality Assurance Engineer. I'm sure everyone who has benefited from Adam's patient support over the years will wish him success in his new role. A sincere congratulations from the OSNews team, Adam! Update: Adam mentions that Red Hat has also hired Mandriva alum Vincent Danen.

Red Hat Enterprise Linux 5.3 Released

Red Hat has released Red Hat Enterprise Linux 5.3, the third update to the current stable version. "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. Customers with a Red Hat Enterprise Linux subscription will receive the Red Hat Enterprise Linux 5.3 update, which is available for immediate download from Red Hat Network." More information including a short video explaining the new features via the subscription model is available here.

Red Hat Extends Enterprise Linux Support

Right after the recent news that Red Hat is offering a new subscription for mission critical deployment that extends the life-cycle for up to 10 years, Red Hat has announced another, that allows the customers to stay in a single point release for up to eighteen months and continue to get updates and support that point release. Matt Asay writes: "Red Hat has set the standard for world class software support, consistently earning top marks with CIOs for its efforts. On Thursday, however, Red Hat outdid itself, introducing a new product support plan called Extended Update Support. In a nutshell, Extended Update Support enables customers to run their mission-critical systems for longer stretches of time without having to take production systems offline to update them."

Red Hat Spacewalk Expands Linux Management

Red Hat's Spacewalk project is getting into place. The project wants to feed development of the Red Hat Network Satellite product for system management. Satellite is a critical tool for Red Hat users as it provides management capabilities for multiple servers for software deployment and updates. Almost six months ago, Red Hat kicked off the Spacewalk project in an effort to create an open source version of Network Satellite that would serve as the upstream project that drives development. According to Red Hat executives, Spacewalk is still in the process of getting aligned with Network Satellite releases in terms of the development model. As well, Spacewalk is now gearing up to replace Network Satellite's proprietary Oracle database backend with an open source database. It's all part of Red Hat's larger efforts to use the open source model effectively in all parts of its business, as well as reducing the costs associated with proprietary databases.

Red Hat Offers Mainframe-class Support

Red Hat has announced a new program where customers would get higher service level guarantees and updates for up to 10 years for a new release instead of the usual 7 years for every release. "The targets for this are the most conservative companies currently on Unix-based systems and with a need for unusual levels of support," said Scott Crenshaw, vice president of Red Hat's Platforms business unit.

Red Hat, AMD Migrate VMs Across CPUs Between Different Vendors

Red Hat and AMD have just done the so-called impossible, and demonstrated VM live migration across CPU architectures. Not only that, they have demonstrated it across CPU vendors. "If you look at the video here, you will see that they did it. Live migration while streaming HD video isn't all that bad a trick mind you, but doing it between a Barcelona, Shanghai and Intel box is. 36 more of these, and we will be in great shape." Only a few months ago during VMworld, Intel and VMware claimed that this was impossible. Looking at the initial reaction, VMware is quite irked by this accomplishment by Red Hat using KVM technology and they are pointing to stability concerns. Red Hat has been a heavy contributor to KVM and acquired Qumranet, the original developers of KVM a while back.

A Closer Look at Red Hat’s Plymouth

Back in July we shared Red Hat's intentions to replace RHGB with Plymouth, a new graphical boot process that is able to benefit from the latest Linux graphics capabilities. Red Hat engineers had primarily designed Plymouth around a forthcoming feature we've talked about quite a bit known as kernel mode-setting, which provides end-users with a cleaner and flicker-free boot experience. In September in The State of Kernel Mode-Setting we then shared more information on Plymouth along with a brief video. Most recently we published another video of Plymouth that shows the tighter integration between the boot process and starting the GNOME Display Manager. Today though we are looking at Plymouth and its different plug-ins along with providing a few more videos.
