Red Hat Announced Beta of Red Hat Enterprise Linux (RHEL) 6.3

Red Hat Announced Beta of Red Hat Enterprise Linux 6.3

Just over four months after the release of Red Hat Enterprise Linux (RHEL) 6.2, developer at RedHat has made a beta of version of RHEL 6.3 available. This beta includes a broad set of updates to the existing feature set and also provides rich new functionality particularly in the areas of virtualization, scalability, storage, file systems, and security. As always, the Red Hat Enterprise Linux 6.3 beta delivers new hardware enablement made possible by our strong relationships with our strategic hardware partners. This beta release has been designed for optimized performance, scalability, and reliability to cater to the diverse workloads running in physical, virtual and cloud environments.

Key Features in the Red Hat Enterprise Linux 6.3 Beta:-

Virtualization-

• A new tool called Virt-P2V that facilitates the conversion of physical Windows or Red Hat Enterprise Linux systems into virtual images to be deployed as KVM guests inside Red Hat Enterprise Linux or Red Hat Enterprise Virtualization.

• Stronger compliance with Payment Card Industry Data Security Standards (PCI-DSS), including the ability to perform secure wipes of virtual machine disks.

• The ability to perform live volume resizing, improving the overall availability of virtualized guests.

Scalability-

• The maximum number of virtual CPUs (vCPUs) has been increased from 64 to 160, which lets you run larger CPU-intensive workloads on the Red Hat Enterprise Linux platform. VMware ESX 5.0 currently support 32 vCPUs.

• The maximum supported memory configuration for KVM guests has been increased from 512GB to 2TB.

File Systems-

• GFS2 enhancements that create faster read-write capabilities for specific use cases.

• Support of O_Direct in FUSE (Filesystem in User Space), which can provide improved performance for certain workloads.

• Simplified configuration and administration for the file system. Integration of automount capability with System Security Services Daemon (SSSD) provides centralized management of configuration data and the ability to improve performance through caching and load balancing. (This feature is a Technology Preview.)

Storage-

• Red Hat Enterprise Linux 6.3 provides full support for Fibre Channel over Ethernet (FCoE) Target. This feature, which was previously provided as a Technology Preview, allows customers to present their Red Hat Enterprise Linux servers as FCoE storage devices. This feature complements the FCoE Initiator support that was delivered in Red Hat Enterprise Linux 6.0.

• The Logical Volume Manager (LVM) now provides support for RAID levels 4, 5, and 6. (Previously, support for these RAID levels was provided through the MD subsystem.) This expanded LVM RAID support simplifies overall storage administration by consolidating all management functions, such as creating volumes, resizing volumes, deploying RAID, taking snapshots, etc., into a single interface. (This feature is a Technology Preview.)

• The LVM now provides the ability to create thin provisioned logical volumes. Previously, storage was allocated when the volume was created, and needed to be monitored for space consumption and expanded manually. In Red Hat Enterprise Linux 6.3, storage is allocated as required, allowing volumes to expand up to the requested size on demand without intervention. (This feature is a Technology Preview.)

Security-

• Availability of a two-factor authentication mechanism, enhancing the overall security available to lock down Red Hat Enterprise Linux environments and enabling compliance with industry standards such as PCI-DSS.

• Expansion of the Advanced Encryption Standard (AES) to provide particular benefits for system performance on multi-processor machines.

Identity Management-

• With native support for netgroups and the services map in System Security Services Daemon (SSSD), Red Hat Enterprise Linux servers can be integrated into centralized systems -- such as Active Directory -- to manage system users.

• The addition of an automembership plug-in streamlines the administration of new users and hosts when they are added into the Identity Management system by automatically placing them into a predefined set of groups, speeding user and host provisioning.

• Performance improvements through session data caching, which lowers the overall load on authentication servers.

Hardware Enablement-

• Software bandwidth management for USB 3.0 for select Intel platforms is now available.

• Compiler optimization for Intel Xeon E5 processor family, which improves the result of string operations, is now included.

• Improvements to memory and I/O breakpoint execution operations within compiler tools are now included.

Developer Tools-

• With the introduction of OpenJDK 7, customers can develop and test with the latest version of open source Java.

LibreOffice Fixes Security Hole In The Binary Microsoft Word (doc) file Format Importer

LibreOffice users ought to update their software: a security hole has been discovered in the code used to import Microsoft Word documents into the open-source productivity suite. The latest version of the software contains a fix for the problem.

A memory corruption-related vulnerability in the import code creates a possible mechanism for virus writers to inject hostile code into vulnerable systems, developers at The Document Foundation warn. The bug was discovered by RedHat security researcher Huzaifa Sidhpurwala and fixed with version 3.4.3 of the package.

LibreOffice 3.4.3 also addresses lesser security problems involving loading Windows Metafile (.wmf) and Windows Enhanced Metafile (.emf) images into documents.

An advisory from LibreOffice on the vulnerability can be found here

VMware vSphere 5 to add cloud virtualization support for Mac OS X Server

The upcoming release of VMware's vSphere 5 virtualization platform is reported to include guest OS support for Mac OS X 10.6 Snow Leopard, indicating new options for enterprise use of Apple's server platform without the now discontinued Xserve.

VMware's plans for the next release of vSphere, as discussed in February at the company's Partner Exchnge conference, have been detailed in a posting by Virtualization.info, including mention of support for Mac OS X Server.

The vSphere product allows companies to build a private of public cloud of pooled infrastructure, offering enterprise planners more flexible capacity management than if they were required to allocate dedicated hardware to every server instance.

The product also helps data center managers to automate disaster recovery plans and monitor and manage performance while accurately reporting the costs needed to provide IT services.

By pooling server hardware, VMware says businesses can reduce their requirements of power, cooling and server storage, cutting energy cost by as much as 80 percent.

Formerly named VMware Infrastructure 4, the cloud-enabled vSphere platform is built upon the company's core virtualization hypervisor called ESXi, which runs as a low level microkernel OS on actual server hardware, and facilitates flexible, virtual deployment of guest OS virtual machines on top, moving around virtual images to use available hardware as necessary.

The product currently supports Microsoft Windows 7, Windows Server 2008, Oracle Solaris 10, as well as enterprise versions of Linux from RedHat, SUSE and Ubuntu. By adding support for Mac OS X Server, VMware will give its enterprise customers an option for virtualizing the deployment of Apple's server features without having to dedicate rack space to Mac hardware.

While Apple has backed out of the dedicated server hardware market, first by discontinuing the Xserve RAID and then by terminating its Xserve rack mounted server, it continues to develop its Mac OS X Server product, with the next major version adding the formerly premium server features to the standard edition.

Mac OS X Server includes WebDAV-based calendar and contact management, easy to use wiki services for building group collaboration tools, and under Mac OS X Lion Server 10.7, will incorporate expanded support for iOS mobile devices, including WebDAV file sharing for iPhone and iPads, expanded Push Notifications for messaging services, and a new Profile Manager that provides setup and management features for iPhone, iPad, iPod touch and Mac OS Lion computers.
