Red Hat's KVM: A better way to virtualize the data center?

When you virtualize your servers, do you divide them by operating system, or is it practical to use a bare-metal hypervisor to support all your x86 operating systems?

That's what Red Hat thinks is the best idea - which is why it thinks you would be better off virtualizing using KVM, included in Red Hat Enterprise Linux.

With Reg users reporting that the cost of licenses, the problems of managing multiple platforms and virtual machine sprawl are hurdles to virtualisation, the enthusiasm for virtualisation - and the success of early efforts - creates its own problems.

But is KVM strictly for Linux specialists, or can it provide performance and management benefits for any data center?

Leftovers: KDE

  • KDE-5_15.09 – september release for Slackware-current
  • Kontact and GnuPG under Windows
    Kontact has, in contrast to Thunderbird, integrated crypto support (OpenPGP and S/MIME) out-of-the-box. That means on Linux you can simply start Kontact and read crypted mails (if you have already created keys). After you select your crypto keys, you can immediately start writing encrypted mails. With that great user experince I never needed to dig further in the crypto stack.

  • KDE 5 Application Dashboard: A fullscreen app launcher that beats the competition
    Fullscreen applications launchers are my favorite kind of application menus, of which there are several to choose from on the K Desktop Environment, or KDE. On KDE 4, available options are the Takeoff Launcher, Simple Welcome, and Homerun.

Fedora: The Latest

  • Flock Rochester
    I’m not going to do a day by day outline of what I did at flock, if I did it would basically be “blah blah blah I talked a lot to a lot of people about a lot of tech topics” and anyone that’s ever met me would have guessed that! It was, as in the past, a great conference. A big shout out to the organisers for an excellent event with two excellent evening events! So I’m going to give a brief summary to my talks and link to slides and video recordings.
  • Day 4 of Flock 2015
  • Write the Docs 2015
    Writing documentation is not only about writing, but actually a lot about layout, accessibility, UX and UI, too. So I actually enjoyed listening to Beth Aitman, for example (here are here slides). Among the most memorable were Elijah Caine with his talk about writing emails, which I really really hope more people could listen to, and Christina Elmore talking about creative problem solving. One of my personal favorites was a lightning talk by Marcin Warpechowski about laptop stickers! TL;DR – stickers are a great way to engage employees and the community! Got me (and actually everybody) excited about stickers even more and willing to create some. GitHub’s octocat also contributed to my feelings about stickers. They actually produce a special version for all conferences they attend! Also I think it was ladies from GitHub taking most the notes (or maybe I just happened to seat behind them ;) ).
