Red Hat Enterprise Linux 7 Released 231

Posted by Soulskill
from the onward-and-upward dept.
An anonymous reader writes: Today, Red Hat unveiled Red Hat Enterprise Linux 7, with new features designed to meet both modern datacenter and next-generation IT requirements for cloud, Linux Containers, and big data. The new version includes Linux containers (LXC), which let Linux users easily create and manage system or application containers, improved MS Active Directory / Identity Management (IdM) integration, XFS as the default file system, scaling to 500 TB (additional file system choices such as btrfs, ext{3,4} and others are available), a new and improved installation experience, managing Linux servers with OpenLMI, enhancements to both NFS and GFS2, optimized network management, bandwidth, the use of KVM Virtualization technology and more. See the complete list of features here (PDF). CentOS 7 shouldn't be lagging too far behind due to recent cooperation between Red Hat and CentOS project.

Mcusanelli (3564469) writes "Rackspace, Cumulus Networks and CoreOS have become members of the Linux Foundation to support open source networking, virtualization and cloud computing. The Linux Foundation said in a statement: 'From the virtualization layer to networking hardware, Linux and open source are critical to modern computing and a new generation of cloud services and applications. Today's new Linux Foundation members are part of this market shift and see open source as the lynchpin for optimal scalability, efficiencies, security and data center savings.'"

oVirt 3.4 Means Management, VMs Can Live On the Same Machine 51

Posted by timothy
from the right-there-in-the-open dept.
darthcamaro (735685) writes "Red Hat's open source oVirt project hit a major milestone this week with the release of version 3.4. It's got improved storage handling so users can mix and match different resource types, though the big new feature is one that seems painfully obvious. For the first time oVirt users can have the oVirt Manager and oVirt VMs on the same physical machine. 'So, typically, customers deployed the oVirt engine on a physical machine or on a virtual machine that wasn't managed or monitored,' Scott Herold, principal product manager for Red Hat Enterprise Virtualization said. 'The oVirt 3.4 release adds the ability for oVirt to self-host its engine, including monitoring and recovery of the virtual machine.'" (Wikipedia describes oVirt as "a free platform virtualization management web application community project.")

darthcamaro (735685) writes "Docker has become one of the most hyped open-source projects in recent years, making it hard to believe the project only started one year ago. In that one year, Docker has now gained the support of Red Hat and other major Linux vendors. What does the future hold for Docker? Will it overtake other forms of virtualization or will it just be a curiosity?"

Ask Slashdot: Configuring Development Environment On a Shared Workstation? 158

Posted by timothy
from the show-me-your-diagram dept.
First time accepted submitter xyourfacekillerx writes "After a long hiatus of developing (ASP.NET), I decided to pick it up again. I need to learn .NET and SQL for my new job (GIS tech using ESRI software). Down the road they need a PHP website, tons of automation tasks, some serious data consolidation, they want mobile apps in theory. This is not my job description, but I'm sure I can do it. Long story short, I need to setup a development environment on my home desktop, so I can do all this in my spare time. Trouble is, I share the machine (Win 8.1, 2.7 dual core pentium something or other, with virtualization support.) I want to avoid affecting the other users profiles. I currently use my profile for music production (Reason) and photography (Photoshop, et al) so it's already resource intensive with RAM, CPU and VMM. I'll be needing to install all of your basic Microsoft developer suites, IIS, SQl Server, ANdroid SDK, Java SDK, device emulators, etc. etc. Plus AMP and finally GIS software. There will obviously be a lot of services running, long build times, and so on. To wit, I wouldn't be able to use my desktop for my other purposes like the music editing. So I need some advice. Would it help to set up all these tools under a different account on the same Win 8.1 install? Or should I virtualize my development environment (and how?), and run the virtual machine side by side? Or should I add a HDD or secondary partition and boot to that when I intend to develop? I am poor ATM, but is there a cheap very mini PC I can place next to my desktop and run all my development software off that, remote desktop into it? I've done a lot of googling the last week and haven't turned up anything, so I turn to Slashdot. Please help me get organized so I can start coding again."

The Quest To Build Xbox One and PS4 Emulators 227

Posted by samzenpus
from the if-you-build-it-they-will-play dept.
Nerval's Lobster writes "Will Xbox One and PS4 emulators hit your favorite download Websites within the next few years? Emulators have long been popular among gamers looking to relive the classic titles they enjoyed in their youth. Instead of playing Super Mario Bros. on a Nintendo console, one can go through the legally questionable yet widespread route of downloading a copy of the game and loading it with PC software that emulates the Nintendo Entertainment System. Emulation is typically limited to older games, as developing an emulator is hard work and must usually be run on hardware that's more powerful than the original console. Consoles from the NES and Super NES era have working emulators, as do newer systems such as Nintendo 64, GameCube and Wii, and the first two PlayStations. While emulator development hit a dead end with the Xbox 360 and PS3, that may change with the Xbox One and PS4, which developers are already exploring as fertile ground for emulation. The Xbox 360 and PS4 feature x86 chips, for starters, and hardware-assisted virtualization can help solve some acceleration issues. But several significant obstacles stand in the way of developers already taking a crack at it, including console builders' absolute refusal to see emulation as even remotely legal."

In Three Years, Nearly 45% of All the Servers Will Ship To Cloud Providers 152

Posted by samzenpus
from the silver-lining dept.
dcblogs writes "IDC expects that anywhere from 25% to 30% of all the servers shipped next year will be delivered to cloud services providers. In three years, 2017, nearly 45% of all the servers leaving manufacturers will be bought by cloud providers. The shift is slowing the purchase of server sales to enterprise IT. The increased use of SaaS is a major reason for the market shift, but so is virtualization to increase server capacity. Data center consolidations are eliminating servers as well, along with the purchase of denser servers capable of handling larger loads. The increased use of cloud-based providers is roiling the server market, and is expected to help send server revenue down 3.5% this year, according to IDC."

Ask Slashdot: How Reproducible Is Arithmetic In the Cloud? 226

Posted by timothy
from the irreproducible-results dept.
goodminton writes "I'm research the long-term consistency and reproducibility of math results in the cloud and have questions about floating point calculations. For example, say I create a virtual OS instance on a cloud provider (doesn't matter which one) and install Mathematica to run a precise calculation. Mathematica generates the result based on the combination of software version, operating system, hypervisor, firmware and hardware that are running at that time. In the cloud, hardware, firmware and hypervisors are invisible to the users but could still impact the implementation/operation of floating point math. Say I archive the virutal instance and in 5 or 10 years I fire it up on another cloud provider and run the same calculation. What's the likelihood that the results would be the same? What can be done to adjust for this? Currently, I know people who 'archive' hardware just for the purpose of ensuring reproducibility and I'm wondering how this tranlates to the world of cloud and virtualization across multiple hardware types."

Amazon Jumps Into Desktop Virtualization With "WorkSpaces" 92

mattydread23 writes "Amazon is getting into the desktop virtualization space. This is potentially huge news for providers like Citrix, but as writer Nancy Gohring points out, the company is starting small. Very small: 'The administrator console only allows managers to provision five WorkSpaces at a time. It's possible that will change when the service becomes generally available. For now, Amazon is accepting sign ups for a limited preview of the service. '"

Ask Slashdot: Tools For Managing Multiple Serial Console Servers? 104

Posted by timothy
from the many-roads-to-rome dept.
An anonymous reader writes "I've recently been charged with updating our existing serial console access tools. We have 12 racks of servers each with a console server in it (OpenGear, ACS, and a few others). Several of these systems host virtual machines which are also configured to have 'serial' management (KVM, virt serial). In total it comes to about 600 'systems.' All the systems also have remote power management (various vendors). Right now our team has a set of home grown scripts and a cobbled together database for keeping this all together. Today any admin can simply ssh into the master, run 'manage hostname console' and automatically get a serial console or run 'manage hostname power off' to cut the power to a system. I'd rather use some tools with more of a community than just the 4 of us. What tool(s) should I move my group onto for remote serial/power management?"

Imagination Tech Announces MIPS-based 'Warrior P-Class' CPU Core 122

Posted by samzenpus
from the check-it-out dept.
MojoKid writes "Imagination Technologies has announced the first CPU based on its new version of the MIPS architecture. The new P5600 chip (codenamed Warrior) is a 32-bit CPU based on the MIPS Series 5 architecture and is designed to challenge companies like ARM in the embedded and mobile markets. Major features of the new chip include: support for 40-bit memory extensions, or up to 1TB of RAM, a 128-bit SIMD engine (Single Instruction, Multiple Data), and Hardware virtualization (MIPS R5 can virtualize other machines in hardware). The P5600 core is being touted as supporting up to six cores in a cache-coherent link, most likely similar to ARM's CCI-400. According to IT, the chip is capable of executing 3.5 DMIPs/MHz in CoreMark, which theoretically puts the P5600 on par with the Cortex-A15."

To make the browser experience authentic, the developers recreated how terminals would draw one character at a time by covering the page in black and then revealing each character by erasing a character-sized rectangle from that cover, one-by-one, line-by-line. They also recreated the sound of typing on older keyboards, specifically an IBM RS/6000 keyboard, by using HTML5 audio elements."

Linux Vendors Push For Open-Source In Hybrid Datacenter Clouds 30

Posted by Soulskill
from the works-better-than-pushing-fresh-mangoes dept.
Nerval's Lobster writes "Linux vendors Red Hat and SUSE are pushing to make sure Linux-based virtual machines are an important part of datacenter-based hybrid clouds. The two are taking significantly different tacks toward the same destination, however. SUSE is using the visibility and cloud hype of VMware by extending its partnership with the virtualization provider to promote its SUSE Linux Enterprise Server for VMware as an alternative operating system for virtual machines running on VMware's vCloud Hybrid Service. Red Hat is happy to include VMware in its plans, but isn't limiting itself either to VMware-based clouds or, in fact, the idea that a Linux vendor has to tag along with a cloud- or virtualization developer to find its place in mixed infrastructures. 'We do not buy into the premise that a private or a hybrid platform based on one vendor's technologies and products is the answer,' wrote Bryan Che, general manager of Red Hat's Cloud Business Unit. More than 25 percent of customers want clouds or datacenter infrastructures using virtualization products from more than one vendor, according to a buyers' guide published in August by market researcher IDC."
