Fedora 13 Expands Linux Virtualization

Linux, Virtualization May 8th, 2010

Virtualization technology has long found a home in Red Hat’s Fedora community Linux distribution. Ever since Fedora 4 emerged in 2005, virtualization technologies have continued to advance in the distro and that remains the case with the upcoming Fedora 13 release set for later this month.

Unlike Fedora’s early virtualization features, which all leveraged the Xen open source technology, more recent Fedora releases have relied on KVM. New KVM performance and scalability features for virtualization will debut in Fedora 13 that will help to push the envelope for large-scale virtualization deployments.

“If you look at Linux virtualization features, Fedora has always been the vanguard for virtualization,” Fedora Project Leader Paul Frields told InternetNews. “We were putting out KVM before anyone else and we were interested in KVM as it seemed like a much more upstream-friendly feature. Although Xen was definitely a virtualization focus for a few years, Xen had some drawbacks.”

Frields noted that from Fedora’s perspective, Xen had become a drain on resources for developers since it took a lot of work to get Xen to work together with the Linux kernel for a Fedora distribution release. He added that, in his view, the code base for Xen didn’t track exactly with the upstream Linux kernel and as a result, there was a mismatch.

“KVM changed all of that because of the fact that it is part of the upstream Linux kernel,” Frields said. “It has allowed us to focus our resources to devote more time in advancing the usability of virtualization.”

Among the new KVM features that will debut in Fedora 13 are KVM Stable PCI Addresses and Virt Shared Network Interface technologies. Having stable PCI addresses will enable virtual guests to retain PCI addresses’ space on a host machine. The shared network interface technology enables virtual machines to use the same physical network interface cards (NICs) as the underlying operating system.

Frields explained that those two new features will make it easier for administrators to automate their work.

“If you’re trying to automate the creation of machines and the way that they share particular bus connections on a host machine, you want to be able to definitely connect it to a particular bus,” Frields said. “When you can predict that, you can take advantage of a greater scale of automation.”

Another new virtualization feature debuting in Fedora 13 is the ^7Frields8^, which is about delivering improved performance. The ^9Frields10^ technology is intended to lower the CPU requirement for Advanced Programmable Interrupt Controller access, or APIC (define), which is used for program timers.

While Fedora is including the new advanced features for scaling virtualization, Frields doesn’t necessarily expect that Fedora will be the platform used for large-scale deployments.

“Fedora is a way for people to have a bit of a crystal ball where they can look into the future of Red Hat Enterprise Linux,” Frields said.

Red Hat recently released the first beta for Red Hat Enterprise Linux 6 (RHEL 6). As is the case in Fedora, RHEL 6 no longer includes Xen, but instead leverages KVM as the key virtualization technology for Linux. Features that first debuted in Fedora releases are now finding a home in RHEL 6.

“When people look at RHEL 6, they will be seeing the very recent past and present of Fedora,” Frields said. “The RHEL roadmap is always oriented towards long-term stability while Fedora will move on and forge new paths and will help define Red Hat Enterprise Linux 7 at some point in the future.”

Hội Người Khuyết tật Hà Nội nhận hỗ trợ máy vi tính chạy nguồn mở

Linux, Work and Life April 1st, 2010

Hôm nay Hội Người Khuyết tật Hà Nội đã tổ chức giới thiệu bộ phần mềm Ubuntu 9.10 với một số đại diện các chi Hội quận huyện. Các máy tính được dùng trong buổi giới thiệu sẽ được các đại biểu mang về dùng cho công tác của chi Hội. Đây là số máy tính được các “cổ động viên” của HanoiLUG phục hồi từ số máy cũ quá hạn sử dụng của AUF, cài đặt Ubuntu để tặng cho Hội NKTHN, kèm theo với bộ sách hướng dẫn sử dụng phần mềm nguồn mở do Bộ KHCN xuất bản. Số máy này được Hội chuyển giao cho các quận huyện xa trung tâm.

Ông Vũ Mạnh Hùng, chủ tịch Hội Người Khuyết tật Hà Nội đã từng là phó GĐ trung tâm tin học của một ngân hàng quốc doanh lớn, cho rằng đưa các máy này đến những nơi có mức dịch vụ hỗ trợ thấp là một cách thử thách, đánh giá khả năng miễn nhiễm virus, tính ổn định của phần mềm Linux có được như tuyên truyền. Giao diện tiếng Việt toàn bộ và phí bản quyền bằng không của bộ phần mềm này cũng là một điều, theo ông VM.Hùng, rất đáng quan tâm để phổ biến rộng rãi trong Hội.

Trở ngại duy nhất với việc phát triển ứng dụng phần mềm nguồn mở trong Hội NKTHN là chương trình đào tạo có tài trợ cho Hội không thể tiến hành tập trung vì điều kiện đi lại khó khăn của các hội viên. Việc đào tạo phân tán tại các cơ sở quận huyện trên địa bàn thành phố hoàn toàn do các trung tâm thực hiện trên nền Windows và các trình ứng dụng tương ứng.

The Top 7 Best Linux Distributions for You

Linux, Weekly Tips February 4th, 2010

There are various approaches to answering this question. The broad answer is: “any of them,” but that’s not very helpful if you’re just looking for a place to start.

The problem is, there never can be one best Linux distribution for everyone, because the needs of each user tend to be unique. Telling someone who’s looking for a good introductory distribution to try Gentoo, for instance, would be a mistake because for all its positive qualities, Gentoo is decidedly not a beginner’s distro.

All too often, Linux aficionados will tend to list the distributions they like as the best, which is fair, but if they are not aware of their audience, they could suggest something that does not meet that person’s needs. Finding a good Linux distribution is like finding a good match in an online dating service: good looks aren’t the only quality upon which to judge a Linux distro.

To help users discover the Linux distribution that’s best for them, this resource will definitively list the best candidates for the various types of Linux users to try. The use-case categories will be:

  • Best Desktop Distribution
  • Best Laptop Distribution
  • Best Enterprise Desktop
  • Best Enterprise Server
  • Best LiveCD
  • Best Security-Enhanced Distribution
  • Best Multimedia Distribution

Once you find the best Linux distribution for your needs, you can visit our Linux Migration Guides to assist you in installing and using the one you’d like to try.

Best Linux Desktop Distribution

There are a lot of Linux distributions that have the primary focus of becoming the next best desktop replacement for Windows or OS X. Of all the categories in this list, this is the most sought-after, and contentious, group of distros.

While it would be ideal to include many distributions on this list, the reality is that there really needs to be just one “best” Linux distribution. For early 2010, that distro has to be Canonical’s Ubuntu.

Ubuntu edges out its closest contenders, Fedora and openSUSE, because its development team is constantly focused on the end-user experience. Canonical and the Ubuntu community have spent a lot of time and resources on bringing ease-of-use tools to this distribution, particularly in the area of installing Ubuntu and installing applications within Ubuntu.

In addition, Ubuntu’s level of support for its desktop products is highly superior, which is important in this class of distributions since it is the most likely to contain users new to Linux. Both the official and unofficial Ubuntu documentation is robust and searchable, a big plus.

Best Linux Laptop Distribution

Laptop distributions almost fall into the same category as desktop users, but there are a number of key differences that make the criteria for evaluating a good laptop distribution important. Power management, docking tools, and wireless ease-of-use are critical to users on the go, as is having a distro that meets those needs.

Right now, the best laptop distribution is openSUSE, one of the lead contenders for the desktop honors. On the laptop, openSUSE shines with great connectivity tools, such as an easy-to-use networking toolset that not only handles WiFi connectivity, but also CDMA/cellular modem connections.

openSUSE also deals with docking stations for laptops very well, including dual-monitor management on the fly. Power management is very granular, which is great for detailing various power needs you might find yourself needing.

Best Linux Enterprise Desktop

This category is replete with great contenders as well, and it’s difficult to highlight just one. At the end of the day, though, the nod must be given to SUSE Linux Enterprise Desktop (SLED).

The reason is simple: while SLED and its primary competitor Red Hat Enterprise Linux Desktop are nearly identical in features and support performance, SLED has the advantage of the openSUSE Build Service, a free and open service that lets applications be built and delivered to SUSE Linux and openSUSE products (as well as Red Hat and CentOS).

This is a very important differentiator in enterprise desktop development, as it means that SLED has the current advantage of application building and deployment in the enterprise arena.

Best Linux Enterprise Server

Again, in this category it really comes down to two main contenders: Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES). Given the pick for the Enterprise Desktop category, you might expect SLES to get the “best of” label here.

But, when all factors for the enterprise server are weighed, RHEL is still the king of this particular hill.

Red Hat edges out Novell with its server product, because RHEL users get a deeply mature distribution, and Red Hat’s support structure is second to none in the enterprise channels.

Best Linux LiveCD

As Linux technology improves, users can easily choose the LiveCD version of practically any of the Linux distros listed here to get the best LiveCD experience for their needs.

There is a specialized class of LiveCDs, however, that offers users utilities and tools for the specific purpose of repairing existing Linux and Windows installations. These distros are very useful to have regardless of what primary Linux distribution you like to use, because in a crisis they are invaluable to own.

In this class of distribution, KNOPPIX is hands-down the most complete and useful distro. Loaded on a CD or USB storage device, KNOPPIX will let you recover from nearly any rare Linux system crash as well as the much-less-rare Windows breakdowns.

Best Linux Security-Enhanced Distribution

Linux is inherently very secure compared to other operating systems, but there’s always room for improvement.

One of the challenges for locking down Linux is if you are not careful, you can take away too much functionality. Another challenge is that the best security-oriented Linux distro, SELinux, is historically known to be difficult to configure correctly. Still, if security out of the box is your priority, this is the best place to begin.

Another approach is the white hat method: using security and forensic tools to examine your existing installation, determine the holes, then lock your system down based on what gaps you find. If you have the time and inclination, this is a great way to do it, because this will get any existing system more secure right away.

For the white hat approach, the best distribution is BackTrack Linux, a dedicated penetration testing distro that will enable you to safely try to crack any system you are caretaking. Its toolset and strong community give it the advantage in this category.

Best Linux Multimedia Distribution

General Linux distributions have come a long way in terms of multimedia performance. Rare is the audio or video file that can’t be played on Linux. Music services such as Rhapsody and video sites like YouTube and Hulu are also standards-compliant and accessible to Linux users.

Still, for those users who are multimedia creators as well as consumers, there are Linux distributions that contain powerful tools for audio and video editing.

The best in this class is currently Ubuntu Studio. For audio, video, and graphic production, it contains a very complete set of tools, as well as format and codec support for a huge range of multimedia formats.

The applications contained in Ubuntu Studio are the same or similar to those used by major studios to create cutting edge work, so users are getting the best apps, coupled with the strong support ethos already found in the Ubuntu community.

In Linux there are as many opinions as there are lines of code. This represents one view of the best in Linux. What’s yours?
