What's JeOS, and Why You Should Care?

Earlier in the month, we announced a Virtual Image for WebSpace. In the note I mentioned that that image included a "JeOS OpenSolaris Prototype", and that effort was Formaly Announcement on Tuesday. JeOSs play an important piece of the virtualization story, so here is a set of links to get you up to speed quickly.


JeOS stands for "Just Enough OS" ("just right" as with the Three Bears). JeOS is usually described as including the JeOS media ( OS core {Kernel,Drives,Login} + OS Mimimum maintenance tools + Minimum user space tools ) + Packages repository (DVD or Network based). The term is relatively new; an early (initial?) reference seems to be from Jordi's; also see Cocktail.

There are different JeOS depending on what OS they are based. Linux is currently a popular base; three variants are Ubuntu JeOS (Wikipedia, WebSite, and How to use it), Oracle (Oracle EL JeOS and Product Page) and Novell (Novell SUSE JeOS, LimeJeOS Blog details).

We believe that there are some benefits in having an OpenSolaris based JeOS, and several folks have been working on that. The Announcement Above is part of that process; more links in follow-up notes.

3 Online Webinars - JSR299, Software Appliances, VirtualBox

We have 3 webinars this week - one in our normal time slot, the other two in new slots to squeeze the topics before JavaOne. The topics are very interesting, I hope you can join us.


The first webinar is on Tuesday and is a reschedule: Pete Muir (Red Hat), the implementation lead for Seam and WebBeans will present on JSR 299, born as WebBeans but now tentatively named Context and Dependency Injection for Java. Check out his recent posts on the availability of the First preview of Web Beans, on the State of Seam, and his prezo at JAX.

The presentation is on Tuesday, May 19th, 10am US Pacific, at TheAquarium Channel. Full details (and recordings) at the Show Page.


POSTPONED - This webinar has been postponed until after JavaOne.

The second webinar is in our normal slot when Chris Kampemeier will present on Software Appliances. Chris, Rudolf, Gabor and others have been working on this some GlassFish-based appliances on a Solaris JeOS and will be discussing the topic, but the exact abstract is still TBD.

The presentation is on Thursday, May 21st, 11am US Pacific, at TheAquarium Channel. Full details (and recordings) at the Show Page.


The third webinar will be by Andy Hall on VirtualBox, the popular type-2 virtualization solution.

The presentation is on Friday, May 22th, 9am US Pacific, at TheAquarium Channel. Full details (and recordings) at the Show Page.

VirtualBox 2.2.0 Now Available

Sun released VirtualBox 2.2.0 on the 8th, two weeks ago and I started playing with it right then but only now I've had the time to write an entry now. This is a major release that includes support for OVF and performance and usability improvements; full details are available in the ChangeLog. This release has had Extensive Coverage; check out Andy's Overview and his Radio Show on the topic (Slides).


VirtualBox is gaining adoption very fast - check the Google Trends (archive). VBox claims 11M d/ls, with more than 25K/day (somewhat less than GF) and 3.5M registrations (that's outstanding). VBox 2.2 is only 50MB and easy to get started, so download it and take it for a test drive.

I'm trying to arrange a presentation for our GlassFish TV Webinars where we can explore the synergies between the projects; in the meantime see the VBox Documentation Wiki, the User Manual and many Blogs at BSC, including this Advanced Set from VirtualGuru.
