Robert Nelson seems to have come out of nowhere with an update to
vzpkg. Before we get started let me briefly review what
An OS Template is what OpenVZ uses as install media so you may install a Linux distribution into a container... since you cannot use a traditional CD-ROM / DVD nor .iso disk image. An OS Template is a
.tar.gz file that represents a somewhat stripped down version of an installed Linux distribution as you would find it installed on a disk filesystem. So, if you want to create a CentOS 5.2 i386 container, you need to find an CentOS 5.2 i386 OS Template.
There are a number of recipes on the OpenVZ wiki for building OS Templates for various Linux distributions but the general process takes several steps and is quite a bit of work. Any tool that can simplify the creation (and updating) of an OS Template is a welcome addition. OpenVZ comes with
vzpkgcache (part of the
vzpkg package) which is designed to facilitate OS Template creation for Red Hat based distributions.
edit: excellent blog feed functiong.
now when my blogs disappear or get messed with i've always got mah cache. of the titling.
and stuff ala redhat inc. ty redhat.
Well now that school has started and things are starting to fall into a rhythm I'm going to be able to post a bit more now. Going from new baby to school starting was rough. So lets see what trouble I can get into now.
I know most here are Ubuntu or Fedora, for the most part. And Bodhi is the MAN! as far as I'm concerned, but,
This article pretty much sums up how I feel about my distro of choice:
I think this video speaks for itself.
As seen on Slashdot and elsewhere is the Bruce Byfield article entitled "The Fedora-Red Hat Crisis".
I'd put this response as a comment to the article on the place where it was published but the site doesn't appear to have a comment system... but given all of the ads there, perhaps I missed it. Anyway... Bruce is inaccurate in a few points that I feel must be addressed.
Perhaps I should have done a better job with my references and as time passes I'll try to improve this... but I wanted to get it out there ASAP.
As has been reported elsewhere, take the front page of Red Hat's website for example, Red Hat has "acquired" Qumranet Inc for a little over $100 million. In a presentation a month or two back for the BozemanLUG meeting... I played some demo videos of Qumranet's Solid ICE product and discussed KVM. Just in case you weren't aware, Qumranet is the company that sponsors the development of the Kernel Based Virtual Machine which got merged into the mainline Linux kernel starting with version 2.6.20. KVM requires hardware support for virtualization to be present in the CPU (Intel VT / AMD-V).
Doesn't Red Hat already use Xen in RHEL?
Yes, Red Hat does use Xen in RHEL although they prefer the term, Red Hat Virtualization. Fedora added support for KVM some time ago... and Red Hat has been working hard to help KVM get to the point where it is mature enough to become a replacement for Xen. They have also been funding a number FOSS virtualization related projects (see oVirt for example) several which support KVM.
I saw an ad for the Utah Open Source Conference on 28 - 30 August in Salt Lake. Is anybody going? I would be tempted except for the economic realities of life in the early 21st Century, and not enough lead time.
Just in case you haven't heard, Dell recently announced a new range of laptops that should be shipping before the end of the year. One exciting new feature is "Latitude On". What is that? Have you heard of Splashtop? If not, check out this video. Latitude is similar BUT unlike Splashtop which is software only, Latitude On includes a hardware subsystem so it uses its own CPU and other resources separate from the main CPU and OS on the system. The advantage is that Latitude On will use way less power... and will supposedly have a battery life of days. Dell didn't make the distro they are embedding but they won't yet say who did. Here's a video from the press conference Dell gave.
I'm a long time reader and subscriber to LWN (Linux Weekly News). LWN is probably the best Linux news site out there with regards to covering kernel development and I often find myself eating up considerable amounts of time sifting through their articles. This week they had an article covering some recent progress in the mainline kernel on checkpointing and restoring of processes and containers of processes... and I wrote a somewhat lengthy response that I decided to share here. I would link to the LWN's original article but it won't be anonymously accessible until next week.
