Booting Windows7 from a virtual hard disk OS file .vhd

Since 2005, VMware and Xen have gradually reduced the performance overheads of virtualization, aided by the Moore’s law doubling in transistor count, which inexorably shrinks overheads over time. AMD’s Rapid Virtualization Indexing (RVI – 2007) and Intel’s Extended Page Tables (EPT – 2009) substantially improved performance for a class of recalcitrant workloads by offloading the mapping of machine-level pages to Guest OS “physical” memory pages, from software to silicon. In the case of operations that stress the MMU—like an Apache compile with lots of short lived processes and intensive memory access—performance doubled with RVI/EPT. (Xen showed similar challenges prior to RVI/EPT on compilation benchmarks.)

In this interview filmed during QCon London 2008, Joe Armstrong, designer of Erlang, speaks on various aspects of the Erlang language, presenting its roots, how it compares with other languages and why it has become popular these days due to its native ability to scale on multi core systems.

Expert to Expert - Erik Meijer and Lars Bak: Inside V8 - A Javascript Virtual Machine | Going Deep | Channel 9

ars Bak is a virtual machine master. He and team have created a Javascript VM, V8, that takes Javascript syntax and produces optimized machine code directly. The result is very performant execution of Javascript. How does V8 work, exactly? What are the basic design decisions that have gone into it's construction? Why is it designed the way it is? How fast can Javascript really run, anyway? How challenging is it to take a language like Javascript and produce highly optimized machine code? Erik Meijer, language designer and fundamentalist functional high priest, discusses these questions and more with Lars. We also talk about the language to machine code translation versus having an intermediate step (like IL) that gets optimized further in runtime context by a JITer. If you want to know the thinking behind the thinking of Javascript compilation, the current state of the art and future directions, then this is for you. Big thanks to Lars Bak for spending time with Channel 9!

Nice chat about V8 concepts with Lars Bak -- interesting ideas on code-as-IR.

An open source, AJAX implementation of the VirtualBox user interface written in PHP.

An open source, AJAX implementation of the VirtualBox user interface written in PHP. As a modern web interface, it allows you to access and control remote VirtualBox instances. Much of its verbage and some of its code is based on the (inactive) vboxweb project. phpVirtualBox was created for people (like me) who prefer not to have to log in to their headless VirtualBox host to administer their virtual machines.
