VMware paravirtualization research
There's been a lot of noise about the politics of the virtualization industry recently. (Ilya Baimetov of Virtuozzo had some of the more cogent comments on this.) Meanwhile, engineers and scientists behind the scenes continue to expand the frontiers of virtualization. Many of those people got together at the Ottawa Linux Symposium last week.
Fraser Campbell at linuxvirtualization.com covered VMware's presentation at the conference by Zach Amdsden:
One of the most interesting things I noted from the presentation were Zach's statements that paravirtualization is inevitable and "paravirtualization provides significant performance gains over traditional virtualization". ... Zach showed benchmarks of a VMI Linux machine running under a VMware product (I would guess a build of ESX 3) and performance was good (around 90% for most metrics).
The paper that was submitted alongside the presentation is VMI: An Interface for Paravirtualization, by Zach Amdsen, Daniel Arai, Daniel Hecht, Anne Holler, and Pratap Subrahmanyam of VMware, and is available on document page 363 (pdf page 371) of Volume 2 of the Proceedings. I'll see if I can get a separate copy to post here.

VI3 Programming with PHP: Part I
VMware's own Richard Garsthagen gives us Part I of his new series on controlling VMware Virtual Infrastructure 3 via the new SDK using PHP. Richard's SDK presentations were very highly rated at last year's VMworld -- be sure and check it out.
This simple example application uses the SDK to check all running virtual machines and query how much free disk space they have within the VM. An query that VirtualCenter today does not do but is possible using the SDK.

Virtualization re-inventing the data center
"Operating systems statically configured on hardware are hard to manage and can be bug prone," commented Diane Greene at AlwaysOn 2006, the Innovation Summit at Stanford. "If you bring in a hypervisor and break the paths [operating systems glued to hardware] apart, the hypervisor manages the hardware and the operating system manages the applications. People will have operating systems tailored to the applications, such as if more security is required. We have ISVs building their own operating systems." Read more about her comments in ZDNet's Between the Lines blog.

Vote for the best appliance
Time is running out! Vote for the best entry in the Ultimate Virtual Appliance Challenge. The deadline for votes is July 31. Each VMTN member can place one vote per appliance, and the winner will receive the $5,000 VMTN Community Choice Appliance award.
The judges are hard at work evaluating 300 GB of entries from across
the globe. All the winning appliances, including the $100,000 first prize
winner, will be announced

People are talking about VMware Server
We released VMware Server for general availability last week. What is the blogosphere saying about VMware Server?
Simply amazing software. I cannot recommend this software enough. Virtualise your server management, run multiple operating systems on the same server, simultaneously. Brilliant software and perhaps the most innovative software this decade?
There are some tools that are just cool, I've tried to put links to some of them in our information pages. There are other tools that are pretty sucky, we try to bash into them for security problems. Then there's tools that make all the other tools more useful. One of these is VMWare.
VMware server is such a pleasure to use!
I've been using a Bugzilla appliance and a DB2 Viper appliance for a while now, and the fact that they just work is quite nice.
I have become a fan of VMware. I have used VirtualPC in the past but became interested in their products when they offered VMPlayer for free. When they offered free usage of the server product and encouraged the VMTN appliance community, I switched.
From my brief experience with the VMWare server, I.m really impressed. I.ve used a number of open-source virtualizers and can see VMWare server with an advantage over them in many categories.
Uses for Virtual Machines * Try new operating systems * Test your software * Set up an office quickly * Small Biz disaster recovery * Build kid boxes * Backup your system * Save Legacy Systems
VMware is out to change a few things in this world, one being how servers serve and the other how developers develop. ... The emerging reality I see is between developing software and consuming betas, between the WinXP and Vista eras, between all the wonderful tools and apps out there all trying to overpopulate startup apps, the system tray and the registry in general, going VM looks seriously good for developers and non-developers alike.
What does this mean to you and me? A whole lot as the cost of hardware is relatively cheap and now you can fully use all your resources of each server. I know of several very large companies that run their production web servers on VMWare servers, I am not going to tell you who as that could be a potential security breach for them. However though this does tell you the robustness of these products.
I eventually settled on VMWare Server. While VMWare Workstation has more advanced features, VMWare Server has many of the key characteristics I was looking for: ability to run headless VMs, snapshots, a good user interface to the VM desktops. I only noticed Workstation's Shared Folders and Team VMs (i.e. groups of VMs) missing.
So, with ALL of that said. I will most likely phase out the rest of my VS 2005 vm's and import them into VMware format in the near future. Though both servers are very close in comparison, VMware still came out on top, showing that their still the best at what they do...and now that there stuff is (mostly) free, there's really no reason to for me use any other tech.
I was actually surprised with the performance of Ubuntu as a guest OS. I didn't expect it to run so smoothly without any noticeable slowdowns. It was my belief that virualisation was hella slow on "normal" computers and I needed at least a 3.0Ghz machine to get some decent speeds with it.

VMware Community Source Partner Event
VMware is holding an event for current and potential partners in our Community Source program. If your company makes hardware, software, storage, or networking products that work with VMware or in a virtual environment, this event is for you.
Attend and learn how you can:
Register now for the VMware Community Source Partner Event July 27th, 2006.

InfoWorld: Virtualization breaks out
InfoWorld has pulled together a Special Report on Virtualization. It's a light overview if you're starting from scratch. This intro article has a table comparing two broad approaches to virtualization. I disagree, however, with describing both VMware ESX Server -- a bare metal hypervisor -- and Microsoft Virtual Server 2005 R2 -- which runs on top of an operating system -- both as "hardware emulation." VMware Server would be a better comparison. And emulation is a different beast than virtualization, but for this kind of primer, I might be splitting hairs. Articles include:
It's also available as a handy dandy 11-page pdf for your offline enjoyment.
While you are at InfoWorld, don't forget to check out Dave Marshall's Virtualization Report blog, a very good way to keep up on this broad and fast-moving industry after you've finished InfoWorld's special report.

sudo apt-get install vmware-player
I was reading this review of VMware Player and Fedora Core, I realized I hadn't blogged that VMware Player is now available in Ubuntu Dapper repositories. Reading the comments, it looks like your mileage may vary, but for most, a sudo apt-get install vmware-player will do the trick. "No tarballs, no compiling kernel modules, no banging rocks together."

Security by virtualization
virtualization.info has a good overview of the uses of virtualization for security, originally published SearchServerVirtualization and linked on the VMTN Blog last week. He covers sandboxing (application isolation), disaster recovery & high availability, forensic analysis, honeypotting, and "a more blended future."
The futures sections in particular are quite prescient. Alessandro has a CISSP certification and is a Microsoft Security MVP -- he's got a good perspective on how security blends with virtualization.
