This entry is quite longer than usual;
it started as a short update on the recent 2.1 release of
but it quickly grew to cover other intertwined announcements.
I could have done several separate posts but a single one seemed more useful, so...
Start with Steve's
What's Up with xVM
or in the
the 5 inter-related areas down from there are:
xVM Ops Center,
VirtualBox has a very fast release cycle
and it regularly adds features and performance and addresses bugs.
The last release was
and it has received very positive press reviews
VirtualBox is a solid hit;

(Community previously here but now at
virtualization solution based on the work of
and this is the area that seems to be in most flux.
Steve addressed some of the points in the
and later in
Free Hypervisor Options.
Quoting from the first entry on feedback from the beta program:
As a result of these and many other observations, we concluded that a general purpose, multi-node solution is required. Thus, we refocused our efforts around use-cases where Ops Center becomes the central way to manage the hypervisor and the underlying hardware. In addition, we've started on a trajectory where we will converge the xVM Server and OpenSolaris lines so that exactly the same codebase is used for both.
Logical Domains (LDOM)
allows the grouping of system resources into logical groups to provide very
cheap, built-in (
virtualization for Sun's CMT systems.
The scope of this technology is more limited than the previous virtualization solutions
but it is very efficient and meshes very well with Sun's hardware story.
A (separate recent announcement was that of
Solaris 10 Branded Zones,
an addition to previous
Solaris 8 and 9
Zones vs LDOMs
for an overview of the two technologies.
Finally there is
VDI - Virtual Desktop Infrastructure
I think of it as SunRay meets VBox:
the goal is to maximize IT infrastructure utilization and improve manageability of desktop deployments and the latest release,
leverages VDI broker, VirtualBox and OpenStorage servers.
ZDNet has a
that ends asking for more publicity on the technology, so... check Markus' series:
Demo Configuration Instructions,
Coralville Adoption Story.
Hope this helps to understand how the 5 pieces relate to each other.
This entry is also a good example of how blogs, wikis and other self-publishing
tools accelerate information flow within a corporation.
All the writeups mentioned above are mini-essays on the different topics;
they are all published directly by the authors and cross-linked via the internet.
Add Blogs.Sun.Com and an Internet Search Tool and I can grab a thread and construct the story...
And, if I get it wrong, somebody will correct me...
It is not fool-proof, but try to replicate this by registering into N\*\*M mailing lists!
Of course, you need some significant level of transparency in the organization; otherwise one needs to get a legal approval
to post anything!
The alternative is to try to replicate the internet dynamics within the corporation, which may work for a very large company
like IBM, but would not work for us at Sun,
and does not help in communicating directly to the customer.
Now back to our short blog entries...
