Virtual operating systems, virtual machines

Filed under
Interviews

Sit tight, Linux Users. User Mode Linux will soon have the same capabilities as Xen in the virtualization arena -- like live migration, says Jeff Dike, author of User Mode Linux. Operating out of the Linux kernel port, UML enables the port to host multiple virtual operating systems.

Speaking with SearchOpenSource.com, Dike described the pros and cons of virtual machines versus virtual operating systems and offers some advice on whether to opt for UML, Xen or VMware.

SearchOpenSource.com: You mentioned that User Mode Linux differs from other virtualization technologies because it's more of a virtual operating system than a virtual machine. How does a virtual operating system compare with a virtual machine?

Jeff Dike: A virtual operating system has greater contact with the host operating system. This allows interactions between guest and host, which would be difficult or impossible with a virtual machine. For example, UML has two file systems [with somewhat different properties], which allow a host directory to be mounted as a UML file system.

Full Story.

In another interesting interview

In another interesting interview at SearchOpenSource.com:

There is a new open source software legal battle brewing. It concerns Red Hat Inc., JBoss, which is now a division of Red Hat, and a relatively unknown company called FireStar Software Inc. Boston intellectual property attorney Tom Carey argues that, for now, users might be better off taking a good look at proprietary software before jumping into open source, if only until the specifics of the case become better known.

Already, there have been conspiracy theories regarding Microsoft/FireStar collusion since Microsoft was a listed partner of FireStar in the past. Is FireStar getting legal assistance from Microsoft?

Carey: There is no evidence of that, but that point is really sort of intriguing, and may pop up in the discovery phase of the litigation. The fun part of the SCO case was that that company was publicly held and had to disclose many of the things it probably did not want to disclose during the course of that trial. With this trial, that kind of information is not going to be available.

That Interview.

Edubuntu Vs UberStudent: Return To College With The Best Linux Distro

Importantly, there are a handful of programs that are on Edubuntu that UberStudent doesn’t have, such as KAlgebra, Kazium, KGeography, and Marble. Instead, UberStudent has a smaller collection of applications but it does include some useful items when it comes to writing papers that Edubuntu does not have. So ultimately, Edubuntu includes more programs that are information-heavy, while UberStudent includes more tools that can aid students in their studies but doesn’t directly give them any sort of information.

Zotac Nvidia Jetson TK1 review

The Jetson TK1, Nvidia’s first development board to be marketed at the general public, has taken a circuitous route to our shores. Unveiled at the company’s Graphics Technology Conference earlier this year, the board launched in the US at a headline-grabbing price of $192 but its international release was hampered by export regulations. Zotac, already an Nvidia partner for its graphics hardware, volunteered to sort things out and has partnered with Maplin to bring the board to the UK. In doing so, however, the price has become a little muddled. $192 – a clever dollar per GPU core – has become £199.99. Compared to Maplin’s other single-board computer, the sub-£30 Raspberry Pi, it’s a high-end item that could find itself priced out of the reach of the company’s usual customers. Read more

New Human Interface Guidelines for GNOME and GTK+

I’ve recently been hard at work on a new and updated version of the GNOME Human Interface Guidelines, and am pleased to announce that this will be ready for the upcoming 3.14 release. Over recent years, application design has evolved a huge amount. The web and native applications have become increasingly similar, and new design patterns have become the norm. During that period, those of us in the GNOME Design Team have worked with developers to expand the range of GTK+’s capabilities, and the result is a much more modern toolkit. Read more
