Porting RHEV-M from C# to Java

A developer from the Qumranet team, developers of the KVM virtual machine and Spice Protocol has written about the team's experience in porting the RHEV-M software from C# to Java as a means of making the application cross platform and open sourcing it. The team considered several options including Mono which they discarded as too immature for the job, and Grasshopper technology was discarded as an option since the goal was to open source it and eventually settled on a semi-automated workflow using Java. Red Hat is well on its way towards the goal of making a cross-platform and open source management tool for managing virtual machines in the servers and desktops.

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."

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 and 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."

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."
