Red Hat pushes out RHEL 6.4 beta bringing Hyper-V driver of Microsoft

December 28th, 2012    Posted in Hyper-V, Internet, Microsoft Hyper-V

Red Hat, the American software company that’s engaged in developing and distributing open-source software products to the enterprise community, has released a beta of its RHEL (Red Hat Enterprise Linux) for its loyal customers.  And this new beta release, which is the 4th minor release of RHEL6, the developers at Red Hat have set up drivers for Hyper-V, the hypervisor by Microsoft, into the distribution of Linux.

Even though the Hyper-V drivers were available for a while now, they did not meet up the requirements of the kernel developers’ until few months back. And probably this was why the Red Hat developers were unwilling to add them in Linux. In addition to Microsoft’s Hyper-V, they have also updated the ESX virtualization solution’s drivers of VMware.

Some Improvements have been made to the SSSD (System Security Services Daemon), which are designed in order to improve the interoperability of the system with Active Directory services of Microsoft. Red Hat also states that they have made improvements to the performance of the Parallel network file system (pNFS), yet the support agreement still excludes the use of the pNFS.

The release of RHEL 6.4 is expected between late January and early February 2013.

Windows Server 2008 trying to catch up with Linux

November 15th, 2012    Posted in Internet, Microsoft Hyper-V, Windows Server

Windows Server 2008 can never become Linux. And it is not likely that Windows could persuade the loyal users of Linux away from the open source OS anytime soon.

However, the Server Core and PowerShell, 2 of the most “talked about” features in Windows Server 2008, have solved the long-lamenting shortcomings of Windows in a Linux-like fashion. And this is expected to ease the concerns of restless Unix administrators to migrate to Linux, stated Al Gillen, analyst of IDC (International Data Corporation).

He also stated that as Microsoft keeps working on erasing the objections (by adding features like Server Core and PowerShell), the harder it would become for the admins in the “Unixland” to claim that Microsoft’s Windows Server does not meet their requirements.

The Windows Server 2008 offers a list of improvements that makes it a much better and much more competitive product in the market, but the above 2 features are specifically introduced to fill the gaps between the functionality of Unix or Linux and Windows.

Importance of Linux virtual machine support

September 12th, 2011    Posted in Microsoft Hyper-V, virtualization

Linux support has been updated in the software of Hyper-V virtualization for Windows Server 2008 R2. When Linux virtual machines run on Hyper-V hypervisor then the software manages to improve relatively weak support. Hypervisor based virtual machines are basically those servers or operating systems upon which virtualization technology has been implemented.

Another name for hypervisor is virtual machine monitor which allows numbers of operating systems to run on a host computer. The best fact about the same is that it can mix various versions of Linux and Windows at the same time. The cost of the customers can be reduced and the continuity of the business can be improved as windows server 2008 Hyper-V provides an end-to-end virtualization platform. Microsoft has also launched the successors of windows server 2003 which is known as windows server 2008.

The most important feature of this new release i.e. Linux support is the support for SMP i.e. symmetric multi-processing which means that on every virtual machine, hyper-V can support up to four processors. In order to complete heavy back-end computation, SMP support plays a vital role in the virtual machines. Even though multi-core processors were prevailing but inclusion of support was not made sooner and later other improvements were also included such as time synchronization between host and virtual machine, failure detection, and improved performance. The performance can be easily improved by supporting Fastpath Boot.

The virtual machines which run on Novell SUSE Linux Enterprise Server 10 SP3, SUSE Linux Enterprise Server 11 and Red Hat Enterprise Linux 5.2 up to 5.5 are provided with support of Linux.  In spite of such appealing features in Linux support, it was still far behind its competitors and as a result Microsoft Company felt the need of improvising the effect of the existing Linux support for virtual machines.

It appeases the Linux community which has threatened to remove support for Microsoft’s Hyper-V in the standard Linux kernel. Therefore we can say Microsoft Company provides a broader scope of opportunities so that their customers can achieve success at a continual rate.
