Virtual operating systems, virtual machines

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.

Android Leftovers

  • Android Candy: Intercoms
    Ever since my "tiny $20 tablet" project (see my Open-Source Classroom column in the March 2015 issue), I've been looking for more and more cool things to do with cheap Android devices. Although the few obvious ones like XBMC or Plex remotes work well, I've recently found that having Android devices around the house means I can gain back an old-school ability that went out of style in the late 1980s—namely, an intercom system.
  • There's a wild prank hidden in Google Maps that insults Apple in the most childishly inappropriate way
    Rawalpindi is a vibrant Pakistani city known for its bazaars, ancient ruins, and array of religious shrines. But if you pay it a visit on Google Maps, you're going to notice something very unusual on the outskirts of the city — the Android "droid" mascot urinating on the Apple logo.
  • There's an Android bot peeing on an Apple logo on Google Maps
    Sick of all the Apple Watch news today? You're in luck, because we have something completely different for you. An image of an Android mascot, also known as an Android bot or Bugdroid, peeing on an Apple logo has been discovered on Google Maps.
  • An Android robot is peeing on an Apple logo in Google Maps
  • An Android is urinating on the Apple logo in Google Maps (update)
    Google and Apple have always had their differences, but a new Easter egg inside Google Maps has just taken their rivalry to a whole new level. As spotted by Team Android, if you head to these coordinates with the regular Map view enabled, you'll see Google's iconic Android mascot taking a leak on the Apple logo. At the moment, it's unclear who created this little piece of mischief and whether Google is taking action. But if this hidden message is any indication, it was snuck through by a member of the public using Google's Map Maker service, rather than a Google employee. Regardless, it's a crazy (and pretty hilarious) addition that's sure to rile some of the employees in Cupertino. Shots fired!
  • Sony's Android TV-powered 4K televisions are ridiculously thin
    Four models from Sony’s 2015 Android TV-powered 4K television range are now available for pre-order, with shipping to begin in May. The Japanese electronics giant unveiled its 4K TV lineup for 2015 at the Consumer Electronics Show in January, but kept pricing and release information to itself, only saying the new sets would be available sometime in the spring. Those details are finally here and the TVs themselves aren’t far off.
