Virtual operating systems, virtual machines

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.

Ubuntu Touch finds a home on a conflict-free, fair-trade, user-maintainable handset

Handset maker Fairphone is teaming up with the community project UBports, which seeks to get Ubuntu Touch on mobile devices. They will be showing off Ubuntu Touch running on the Fairphone 2 during Mobile World Congress, which starts February 27 in Barcelona. While Ubuntu is probably not the first name that comes to mind when you think of mobile devices, the phone in question offers some compelling features. “UBports Foundation will be showcasing its work at the Canonical booth, the company behind Ubuntu. Canonical is planning to tell about the latest developments around the convergence of its devices and UBports Foundation will share its mission ‘Ubuntu On Every Device’ with the visitors,” UBports said in a February 8 press release. Currently, UBports’ website lists three devices as “fully working as daily drivers:” The OnePlus One, Nexus 5, and the Fairphone 2, with the latter showing all parts as functioning with Ubuntu Touch, save the GPS radio. (Interestingly, the UBports project website for the Fairphone 2 still lists the GSM radio [in addition to the GPS] as a work in progress. However there is a video of two people talking with the handset, so it’s likely the Fairphone 2 project website is out of date.) The website also has instructions for flashing Ubuntu to the Fairphone 2. Read more

  • “Hi, I’m jkh and I’m a d**k”
    Yesterday, I was privy to a private email message discussing a topic I care deeply about. I contacted the author and said “You really need to make this public and give this a wider audience.” His response boiled down to “if I wanted it to get a wider audience, I was welcome to do so myself.” So here’s my first ever guest post, from Jordan K Hubbard, one of the founders of the FreeBSD Project. While this discussion focuses on FreeBSD, it’s applicable to any large open source project.
